| Abstract: | A new catalogue of extended radio sources has been prepared based on arcminute-resolution 1420-MHz images from the Canadian Galactic Plane Survey (CGPS). The new catalogue provides both 1420- and 408-MHz flux density measurements on sources found near the Galactic plane in the second quadrant of our Galaxy. In addition cross-identifications are made with other major radio catalogues and information is provided to facilitate the recovery of CGPS image data associated with each catalogued source. Numerous new radio sources are identified and the catalogue provides a comprehensive summary of both newly discovered and previously known H ii regions and supernova remnants in the outer Galaxy. The catalogue should be of use both for synoptic studies of Galactic structure and for placing higher resolution observations, at radio and other wavelengths, in context. |
