Abstract:
We present the results of a search for new Galactic sources from the
BG catalogue (Fanti et al., 1974A&AS...16...43F 1974A&AS...16...43F). The observations
were made with the Westerbork Synthesis Radiotelescope operating at
1.4GHz, using the short cuts technique. The adopted selection criteria
for the observed sample are discussed in detail. For reducing the data
we have adopted the Clean and Restore technique. We have also tested
the capability of this technique in reproducing the total flux density
for the very extended structures. A catalogue of the sources present
in each field was produced ; the relevant information about
observations and reduction characteristics are given.

Note (1): When this field is blank, the followed position is that of
the field for BGNNNNNN names, and that of the field source for 32WNN
names. Capital letters (A to E) are for structures related to the BG
sources. Small letters (a-n) are for the small structure components.
Note (2): Notes:
1: peak position
2: diameters from the lowest contour in the map. In this case, the
positions is that of the radiocentroid, unless the peak position
is specified.
