The Clark Lake 30.9 MHz Galactic plane survey

Abstract

The galactic plane has been mapped at 30.9 MHz with the Clark Lake TPT telescope giving unprecedented resolution for such a low frequency. The synthesized beam is 13arcmin.0×11arcmin.1 at the zenith. Contour maps and a source list are presented for the regions 350° ≤ l ≤ 59°, 84° ≤ l ≤ 97°, and 133° ≤ l ≤ 250°, with |b| ≤ 2° - 3°. The source list contains integrated flux densities and positions for 702 discrete emission regions. Sensitivity is confusion limited and varies from ≡5 Jy beam-1 in the inner Galaxy to ≡1 - 2 Jy beam-1 toward the outer Galaxy.
