Summary.- A systematic search for certain objects (NGC + IC galaxies, all galaxies with a diameter larger than about 1.0 arcmin, all disturbed galaxies, all star clusters in the Budapest Catalogue, and all listed planetary nebulae) has been carried out by means of the ESO(B) Atlas, covering the southern sky from -90 to -17.5 deg. A total of 18438 objects is listed; of these, about 60% for the first time. Magnitudes and radial velocities are also given for a total of 2102 galaxies.

1. The ESO(B) Survey and Atlas

The ESO 1m Schmidt telescope became operational at La Silla, Chile, towards the end of 1972. One year later, the 48" Schmidt telescope of the Science Research Council of the United Kingdom started observations at Siding Spring, N.S.W., Australia. Subsequently, a collaboration was initiated between ESO and SRC which will eventually result in the publication of a two-colour Atlas of the Southern Sky from declination -90 to -20.

In view of the comparatively long period necessary to complete the two- colour survey, an urgent need was felt for some means to provide a more rapid first look into the southern sky. This would significantly accelerate the identification of thousands of radio and X-ray sources which had already been catalogued in the part of the sky not covered by the Palomar Atlas.

It was therefore decided that the ESO Schmidt telescope should first under- take a rapid survey of the southern sky in a blue waveband similar to the standard Johnson (B) colour. This survey has now been finished and utilizes un- sensitized IIa-O plates in combination with a 2 mm GG 385 filter. The survey is referred to as the ESO(B) Survey (also termed the 'Quick Blue Survey') and covers 606 fields distributed at 5 deg centres from -90 to -20. The nominal field centres are given in Section 7. Further details may be found in the paper by West and Schuster (1982).

Each plate measures 30 x 30 sq cm and has a scale of 67.52 arcsec/mm. The limiting magnitude for a 1h exposure is approximately 21.5.

The original plates were reproduced at the ESO Sky Atlas Laboratory in a two- step operation. First, an intermediate, positive copy was made on Kodak Process Plates at a background density of 1.30 D (ASA diffuse). From this positive, on-glass (Kodak Process Plates) and on-film (Kodak 4427 film) negative copies were made. It was found that a background density of 0.35 D (ASA diffuse), ir- resepective of the sky density of the original negatives, optimises the repro- duction of faint objects on the negative Atlas copies.

2. Search for Objects

In order to provide the astronomical community with identification of objects of certain interest that are seen on the ESO(B) Atlas, a collaboration was undertaken between ESO and the Uppsala Observatory.

The aim of this joint programme was to perform a systematic, thorough and homogeneous search of the 606 plates contained in the ESO(B) Atlas.

The actual search was carried out at the Uppsala Observatory by means of a glass copy of the ESO(B) Atlas. The following objects were found, listed and described:

To facilitate the examination of the plates, special survey machines were built at Uppsala. They are equipped with zoom microscopes, permitting enlargements from 5 to 30 times. The (X,Y) coordinates of the objects, including a number of astrometric stars, can be measured with an accuracy of about 0.05 mm. The (X,Y) coordinates were transformed to (R.A., Decl., epoch 1950.0) by a computer programme.

The (X,Y) coordinates were measured relative to four reference crosses that were exposed on the original plate just before the stellar exposure. They are situated at 1.2 cm from the plate edge at the centre of each side. The plate centre is defined as the intersection point of straight lines connecting the crosses.

The lists of objects were published in Astronomy and Astrophysics Suppl. Ser. (EU:1 to EU:9, 1974 to 1981), with a total of 18438 entries. After the completion of the last list (Lauberts et al., 1981b), it took another year to produce a thoroughly corrected and updated version of the catalogue. As a result of an extensive literature search, the present catalogue also includes magnitudes and radial velocities for a total of 2102 galaxies. At the same time, a computer readable version has also been prepared and is now available on magnetic tape.

   9. Plate Data
The printed catalogue includes the following data:
Column:
 1: line a:  R.A. and Decl. for the epoch 1950.0, also serving as
	     reference numbers for an individual object
    line b:  Identification
 2: line a:  Survey field No. - Object class - Running No.
    line b:  Identification (continued)
 3: line a:  Galactic longitude
    line b:  Galactic latitude
 4: line a:  X (mm)
    line b:  Y (mm)
 5: line a:  Major diameter (arcmin)
    line b:  Minor diameter (arcmin)
 6: line a:  Position angle (degrees, measured from north towards east)
    line b:  Coding of morphological types for galaxies
 7: line a:  Classification (for galaxies in the Hubble system)
    line b:  Description
 8: line a:  B magnitude (total if m.e. is given)
    line b:  m.e. for B (if <1) or aperture in arcsec (if >1)
 9: line a:  Reference to B
    line b:  Reference to B-V and U-B if not common with B
 10 line a:  B-V colour
    line b:  U-B colour
 11 line a:  Heliocentric radial velocity (km/s)
    line b:  m.e. of radial velocity
 12          Reference to radial velocity

Further information about the listed data: Column 1, line a: The transformation (X,Y) to (R.A., Decl.) was obtained by measuring 7 SAO stars in each field and then utilizing the formulas given by Luyten and La Bonte in the Proceedings of the Conference on the Role of Schmidt Telescopes in Astronomy, 1972, p. 33 (Ed.: U. Haug, Hamburg-Bergedorf). The mean errors as derived from the standard stars and from objects in over- lapping areas, amount to about 3" in each coordinate.
Column 1, line b: N=NGC, I=IC, M=Messier. GCl and OCl refer to the Budapest catalogue of star clusters, PK refer to the Perek-Kohoutek catalogue of planetary nebulae. Other symbols are explained in the reference list of abbreviations.

Column 2: The survey fields are numbered from No. 1 (South Pole) to No. 538-606 (dec. zone -20), see plate data in Section 9. Object class: G=galaxy (galaxies), IG=interacting galaxy (galaxies), EN=emission nebula, PN=planetary nebula, SC=star cluster, SNR=supernova remnant, A=asteroid, C=comet. The running numbers are introduced for practical purposes, originally according to R.A. but not necessarily so after revision. Contrary to the ordering system adopted in lists EU:1 through EU:9, an individual object is here designed according to the Parkes system, and should be referred to as e.g. ESO 000013-8037.5.

Column 3: The galactic coordinates were determined from (R.A., Decl.) in the new system with the galactic north pole at R.A.=12h49m, Decl.=+27.4 deg (1950.0) corresponding to the position of the plane of the neutral hydrogen in the Milky Way system. The zero meridian of the galactic longitudes goes through the new north pole having the position angle of 123 deg in the equatorial system for 1950.0.

Column 4: The rectangular X and Y coordinates (in millimeters) are given with reference to the plate centre, as defined by the four crosses at the middle of each plate side (positive X towards east, positive Y towards north). In a few cases where crosses are missing, X and Y refer to recomputed positions of the crosses. The accuracy of the coordinates is indicated by the number of decimals in X and Y, for instance, X=-82.6, or X=-83.

Column 5: Diameters (in 0.1 arcmin) were measured by using a Bausch and Lomb magnifier with a magnification of 7 and a specially construed measuring scale graded to 0.2 min of arc. The diameters refer to the maximum extent of features which may be described as belonging to the object. Uncertain values have been indicated by a colon. A colon is also appended to total diameters for close pairs, triplets or multiple systems which are difficult to resolve. As a rule, diameters were not measured for other objects than galaxies or new stellar clusters discovered on the survey plates. A comparison with RC2 (D25) diameters shows that galaxies measured on the ESO(B) Atlas plates extend to a surface magnitude slightly fainter than 25 per sq arcsec.

Column 6, line a: The position angle refers to the major axis of elongated galaxies.

Column 6, line b: The coding is according to the Second Reference Catalogue of Bright Galaxies (RC2), except that type S... is coded +5 and type S.../Irr is coded +7.

Column 7, line a: The estimated Hubble class corresponds to the well-known "tuning-fork" classification, with the class SBO added. All elliptical galaxies have been denoted by the symbol E, regardless of ellipticity. In some cases a more detailed classification has been possible following the scheme given in RC2.

Column 7, line b: The description has been kept as concise as possible. Additional information may be found in the Notes Section (indicated by *, in field order), or in other well-known catalogues according to the following system:
1=Galaxy listed in the Morfologiceskij Katalog Galaktik (Morphological Catalogue of Galaxies) by Vorontsov-Velyaminov and Arhipova (1968)
2=Galaxy listed in the Reference Catalogue of Bright Galaxies by de Vaucouleurs and de Vaucouleurs (1964), or Galaxy listed in the Second Reference Catalogue of Bright Galaxies (RC2) by Corwin, de Vaucouleurs and de Vaucouleurs (1976)
V=Galaxy reproduced and listed in the Atlas i Katalog Vzaimodejstvujuscih Galaktik (Atlas and Catalogue of Interacting Galaxies) by Vorontsov- Velyaminov (1959)
A=Galaxy reproduced and listed in the Atlas of Peculiar Galaxies by Arp (1966).

Columns 8-12: References to magnitudes and radial velocities are selected to give the most recent source for each object ( the literature survey was terminated January 1982). In some cases the original data have been analyzed further to meet the specifications stated in this catalogue. For instance, Bertil Dyvell, Uppsala, applied the magnitude-aperture relations (RC2) on data from multiaperture UBV photometry of galaxies (ref 30) to derive total (asymp- totic) B magnitudes for about 30 new objects.

3.2. Magnetic tape version

The magnetic tape version of the catalogue is organized in two ASCII files, with a total of 1214 records; the blocksize is 2880 bytes per record. The approximate length of this tape is 300 feet at 1600 bpi.

The first file contains Sections 1-7, 61 records, 80 characters per line.

The second file contains the main catalogue (Section 8), 18438 entries in 1153 records, 90 characters per line, two lines per object.

4. Acknowledgements

I am grateful to Professor Erik Holmberg who introduced me to this survey work and supported me during all these years. I have had many stimulating discussions with Peter Nilson, who greatly inspired me through his pioneering work on the Uppsala General Catalogue of Galaxies. Much of the final analysis and the preparation for publication was done during my stay at the European Southern Observatory, and I wish to thank the staff there for their hospitality. I also wish to thank several collegues, especially Harold Corwin and Richard West, for many helpful comments on the first draft of this catalogue. Uppsala Data Centre, with the assistance of Erik Onnela, did the extensive keypunching on cards. My sincere thanks are due to the expert work of Hans-Emil Schuster, Oscar Pizarro and Guido Pizarro who took all the Schmidt plates for the ESO(B) Atlas.

The main data of importance for the users of the ESO(B) Atlas are listed in Table 4 in the paper by West and Schuster (1982). For convenience it is reproduced here with the omission of original column 3 (galactic coordinates of the nominal field centre) and column 10 (Julian Date at the middle of the exposure). The table contains observational data for the Quick Blue Survey (QBS) plates which were finally accepted for the Atlas. Note that some copies of early QBS plates were withdrawn and replaced with copies of plates of higher quality (see end of this table). The columns are:
