***Attention***If you downloaded your 7C_final.dat catalogue before 25 January 2008 it will contain a spurious negative value of NMAX in row 28028. As from 25 January 2008 this minor typo has now been corrected and the corrected versions of 7C_final.dat.gz and ReadMe file documenting it are now available by ftp
The main 7C survey at 151 MHz with resolution 70×70 cosec(declination) arcsec2 (EW×NS) covers a large part of the northern hemisphere above declination 30°, excluding the Galactic plane.There is now a final unified non-redundant catalogue for this main survey in ASCII format together with a CDS-style ReadMe file, both available by ftp from MRAO. The catalogue has been constructed from the 100 or so survey fields analysed in the series of papers detailed below. The sensitivity of the survey is not uniform so, as well as describing the data format, the ReadMe file gives some guidance on the limiting flux density and completeness each of the individual catalogues from these contributing fields. A paper describing the construction of the final catalogue has been submitted to MNRAS.
Note that there are completely separate 7C catalogues for the Northern Galactic Plane 7C(G) and for the lower-resolution LOW-DEC 7C survey
The individual 7C source lists used in the construction of the main catalogue
are available here at MRAO in a standardised format; you can retrieve
all of them by ftp or
single sections from the ftp link beside each section below.
(Note that the lowdec survey at intermediate resolution
108×108 cosec(dec) arcsec2 is a separate
entity and has its own standard format.)
Caveat ! Journal tables retrievable from the data centres and via the literature reference links listed below are in the same format as printed in the journal (where applicable), which in some cases will be non-standard with respect to the overall survey.
