Canadian Galactic Plane Survey (CGPS)
Observations of the 21cm spectral line from atomic hydrogen (HI) and radio continuum emission at 1420 MHz
were obtained using the Dominion Radio Astrophysical Observatory (DRAO) as part of the Canadian Galactic Plane Survey (CGPS). The surveys cover Galactic longitudes 63° < l < 175°
and latitudes -3.5° < b < 5.5°
.
The resolution of both the continuum and HI data is 1
arcminute.
CADE currently only serves a HEALpix map of the HI integrated intensity emission. This HI map is constructed by integrating the HI spectral line cube over all 272
channels (each with a velocity resolution of 1.3 km/s
).
The HI data has units of K km/s
. The continuum data has units of K
.
