J/ApJS/68/715 J/ApJS/68/715 Clark Lake 30.9MHz survey N E Kassim Astrophys. J. Suppl. Ser. 68 715 1988 1988ApJS...68..715K galaxies: structure Galaxy: general radio sources: general 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 synthetized beam is 13.0'x11.1' at the zenith. Contour maps and a source list are presented for the regions 350deg<l<59deg, 84deg<l<97deg, and 133deg<l<250deg, with |b|<2deg-3deg. The source list contains integrated flux densities and positions for 702 discrete emission regions. Sensitivity confusion limited and varies from ~5Jy/beam in the inner Galaxy to ~1-2Jy/beam toward the outer Galaxy.
