5. Results

The results of the survey are presented in the form of contour maps and in addition a list of compact sources is given, following the presentation of the first survey section in Paper I. As described in Paper I we have decomposed the survey maps into a "source component" and a "diffuse component". The sum of both components gives the measured absolute temperature for any position. Figure 3 (click here) shows the "source component" in Galactic coordinates with a 2tex2html_wrap1170 grid of equatorial coordinates (Epoch 1950.0)
superposed. The following contour intervals are shown:


Figure 4 (click here) shows the "diffuse component" for the same fields as Fig. 3 (click here), but equatorial coordinates are shown for Epoch 2000.0. These intensities include the all-sky background temperature of 2.8 K. Contours are shown every 50 mK and are labelled every 250 mK.

A list of small diameter sources was derived by fitting a single elliptical or a circular Gaussian in small area around individual sources. Only sources with fitted flux densities exceeding 160 mK TB (or 79 mJy/beam) and sizes smaller than 16tex2html_wrap1184 have been included. We have calculated an integrated flux density for all sources based on the peak flux density and the fitted size. The list of 1830 compact sources is available in electronic form at the CDS (anonymous ftp The list is merged with that of Paper I (see description of individual columns), where 884 sources have been fitted with peak flux densities exceeding 98 mJy or 200 mK TB. Because of residual sidelobes near to CAS A we have not tried to fit sources within the area tex2html_wrap_inline1362 and tex2html_wrap_inline1364. CAS A itself is so strong that nonlinearities of the receiver make a flux determination unreliable.
