Abstract:
Arcminute-resolution radio continuum images at 408 and 1420MHz from
the Canadian Galactic Plane Survey (CGPS) have been used to reexamine
radio sources listed in the Kallas and Reich (1980A&AS...42..227K 1980A&AS...42..227K)
catalogue. A sample of point sources with flat or rising spectra
between 408 and 1420MHz has been compiled, and within this sample
likely Gigahertz Peaked Spectrum sources have been identified.
