Description


We present the results of a deep survey of six fields with the Westerbork Synthesis Radio Telescope at 327 MHz. In total we have detected ~4500 sources brighter than our 5-sigma noise level, which ranges from 2.4-3.5 mJy/beam, over an area of ~95 square degrees. For four fields we also obtained 608 MHz observations, for the remaining two fields 608 MHz observations were already available. We present the source catalogues at both frequencies and derive source counts and spectral indices. The data were calibrated using the DWARF redundancy package and absolute calibration is based on 3C286, using a flux of 26.93 Jy at 327 Mhz and 21.47 Jy at 608 MHz. The source parameters were determined using a gaussian fitting procedure for all but the most complex sources and statistical corrections for noise bias were applied. As part of my PhD-thesis at Leiden Observatory I made the following surveys at 327 and 608 MHz using the Westerbork Synthesis Radio Telescope: -------------------------------------------------------------------------- 64W2: Lynx, 327 MHz only (this field has been mapped at this frequency before by M.J.A. Oort (thesis), I've added a 2 after the W to indicate the revised list), numbers do not correspond because the present survey is more sensitive. 69W : Draco, a survey of 2 overlapping fields at 327 MHz and 6 fields at 608 MHz. 70W : Umi, 327 MHz only, one field. 75W : OH471, one 327 MHz field and three 608 MHz fields 76W : Cam, one 327 MHz field and three 608 MHz fields -------------------------------------------------------------------------- Sources detected at both frequencies have corresponding numbers in the 327 MHz (92cm) and 608 MHz (50cm) lists. Multiple sources are indicated by a '*' after the name, their components by 'A','B', etc. Components of multiple sources do not necessarily correspond between the two frequencies, also in some cases one or more components may not be detected at the other frequency. The .tex files are in plain TeX format The .dat files were written with the following format (fortran): FORMAT(A8,1X,F9.2,1X,F4.2,1X,F9.1,1X,F4.1,1X,F8.2,1X,F7.2,1X,A2, 1 1X,F5.1,1X,F4.1,1X,F4.0,1X,F3.0,1X,F5.1,1X,F5.2,1X,F7.2, 1 1X,F5.2,1X,F5.2)
