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 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.
