Abstract

The Dominion Radio Astrophysical Observatory, in collaboration with an international Consortium of astronomers, has carried out a high-resolution survey of the atomic hydrogen and radio continuum emission from our Milky Way galaxy. The observations of 373 fields with the DRAO Synthesis Telescope are presented in sixty-eight 5 deg x 5 deg mosaics, covering Galactic longitudes from L = 63 to 175 degrees and latitudes from B = -3.5 to +5.5 degrees and a latitude extension to B = +17.5 degrees between L = 100 to 116.5 degrees, with a resolution as small as 1 arcminute. For each mosaic (1024 x 1024 pixels), atomic hydrogen observations are presented as a data "cube" with 272 spectral channels having a velocity resolution of 1.3 km/s. Stokes I continuum images at 1420 MHz and 408 MHz are produced, as well as selected Stokes Q, U and V images at 1420 MHz. Complementary images in the four IRAS infrared bands and data cubes of CO (J=1-0) emission have also been created as part of the Survey.Original acknowledgement for data: This HiPS has used data from the Canadian Galactic Plane Survey, a Canadian project with international partners, supported by the Natural Sciences and Engineering Research Council
