Description:
We present a catalogue of the 408MHz and 1420MHz radio sources in the
region centered near Right Ascension 4h58m and Declination 46degrees
(epoch 1950), i.e. near the supernova remnant HB9. The observations
were made with the Synthesis Telescope at the Dominion Radio
Astrophysical Observatory, near Penticton, Canada. 494 sources at
408MHz and 255 sources at 1420MHz were detected. 408-1420MHz spectral
indices for 101 common sources were derived. The 408MHz source list
was compared with the 4850MHz sources from the Green Bank catalog.
Spectral indices were determined for 165 common sources. We also
compared the source lists with the IRAS and ROSAT point source
catalogs for that region and have identified 16 radio sources with
IRAS point sources and 3 radio sources with X-ray sources.
