Objects that were considered to be "over merged" in the first catalog were deleted from that catalog and the entries for their various subcomponents were taken from a catalog with a higher detection threshold. ... The number of objects added and deleted for the different catalogs were WFPC2: 24 deleted, 31 added; STIS: 26 deleted, 8 added; and NICMOS: 14 deleted, 29 added. ...

Detailed identifications of the FIRST (and NVSS) radio sources are carried out for 26 rich Abell clusters of galaxies in the framework of the announced project (A.G.Gubanov et al. 1997, in ``Problems of modern Radio Astronomy'', XXVII Radio Astronomy conference, St.Petersburg, V.1, P.168). ... Identification of radio sources in clusters of galaxies"). Identifications are performed for all radio sources within Abell radius of cluster of galaxies (3 Mpc for the Hubble constant of 50 km/s/Mpc). ...

The process of determining the number and characteristics of sources in astronomical images is so fundamental to a large range of astronomical problems that it is perhaps surprising that no standard procedure has ever been defined that has well understood properties with a high degree of statistical rigour on completeness and reliability. ... In this analysis we present results from testing such algorithms as implemented in the SExtractor, Selavy (Duchamp), and sfind tools on simulated data. ...

... The stars examined here were primarily culled from two lists of X--ray sources in Orion. ... The second region is two degrees in extent east--west and ten degrees north--south with Orionis being near the northern edge. ... In the end, two main regions were chosen for monitoring: stars near Orionis and stars northwest of the belt of Orion. ... The PSPC identified 22 sources within 15 of Orionis in addition to the sources listed in Table 1 , giving a total of 85 X--ray sources in the Orionis region. ...

... The task first computes a background image in order to identify pixels that may be part of a source. The task uses two different algorithms for detecting ``point'' and ``extended'' sources. ... This is necessary because some faint ``point'' sources may have been missed by the point-source detection algorithm, but picked up by the extended-source detection algorithm. ... When the detection process is finished a check is made on extended sources to see if they can be split into two or more sources. ...
