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)
    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.
