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 is confusion-limited and varies from
∼ 5Jy/beam in the inner Galaxy to ∼ 1-2Jy/beam toward the outer Galaxy.
