The Canadian Galactic Plane Survey Pilot Project

The Canadian Galactic Plane Survey (CGPS) pilot project surveyed the W3/4/5/HB3 Galactic Complex in the Perseus spiral arm using the Dominion Radio Astrophysical Observatory's (DRAO) synthesis telescope (ST). Details of the observations can be found in Normandeau et al (1997, ApJS 108, 279). The abstract and the paper are available.

Observations were made simultaneously at two radio continuum frequencies, 408 MHz and 1420 MHz, as well as in the 21cm spectral line of atomic hydrogen (HI). The gif files of the radio continuum images can be viewed by selecting one of the following options:

The spectral line data can be viewed channel by channel by selecting the desired velocity below.
