The DRAO Galactic plane survey. I. l = 1400, b = 00

Observations of part of the Galactic plane centred on l = 1400, b = 00 made with the DRAO Synthesis Telescope at 408 MHz and 1.42 GHz (both continuum and hydrogen line) as a part of a Galactic-plane survey are presented. At 408 MHz a circular region of radius 40 has been mapped with a resolution of ≅ 3.8 x 3.4 arcmin2 (NS x EW), which provides details of 282 compact radio sources down to a flux density of ≅ 50 mJy and reveals in considerable detail the extended emission in this region. At 1.42 GHz a circular region of radius 103 has been mapped in continuum emission with a resolution of ≅ 1.1 x 1.0 arcmin2 (NS x EW), revealing 81 compact sources down to a flux density of ≅ 6 mJy. Hydrogen-line maps of a circular region of radius 10, smoothed to angular and velocity resolutions of 2 arcmin and 8 km s-1 respectively, are also presented. For both the continuum and the line maps, the Synthesis Telescope data have been combined with low-resolution single-antenna data to provide maps that are sensitive to emission on all scales down to the resolution of the Synthesis Telescope maps
