# 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`.
