Scientific paper

The DRAO Synthesis Telescope has been designed for imaging with excellent sensitivity to extended structure of low surface-brightness. Able to map HI emission with an angular resolution of 1(') , it is a research tool for investigations of the ISM in our own and nearby galaxies. The telescope operates simultaneously in three bands: the 21-cm HI line, and 1420 and 408 MHz continuum. Seven antennas of diameter 8.5m cover EW baselines from 13m to 600m. Field of view at 1420 and 408 MHz is ~ 2(deg) and ~ 8(deg) ; angular resolution is 1(') and 3.5(') EW, extended by cosecdelta NS. The spectral line correlator has 256 channels, with overall bandwidths from 0.125 to 4 MHz ( ~ 26 to ~ 840 kms(-1) in the HI line). Polarimetry is a standard facility at 1420 MHz continuum. The principal project of the Synthesis Telescope is the DRAO Galactic Plane Survey, a systematic mapping from l=75(deg) to l=145(deg) , -3.5(deg}
