Abstract:
We present the first images of the Galactic plane (GP; |b|<5{deg},
-15{deg}<l<255{deg}) at 8.35 and 14.35 GHz. These observations used the
National Radio Astronomy Observatory-NASA Green Bank Earth Station to
survey the sky simultaneously at these frequencies. These are the
first results from the GP survey observations, a program to monitor
the sky at 8.35 and 14.35 GHz. The GP survey series is intended to
detect short-lived radio sources. We present four independent
observations of the Galactic plane, combined to provide a set of
reference images of the Galactic plane. The first survey, GPA, covers
0.82 sr (6.5%) of the sky. A source list is presented for all sources
brighter than 0.9 Jy at 8.35 GHz and also for all sources brighter than
2.5 Jy at 14.35 GHz. The FITS format images, residual images, source
lists, and archive data are available over the Internet. Later papers
will present the results of the variable source search.
