GP8.35/14.35 ivo://nasa.heasarc/gpa NASA/GSFC HEASARC Langston et al. 2026-10-09 NASA/GSFC HEASARC help desk heasarc-vo at athena.gsfc.nasa.gov Survey Source This table contains results from the first Galactic Plane (GP) Survey at 8.35 and 14.35 GHz (3.6 and 2.1 cm). In this project, the first images of the GP in the galactic latitude range |b| < 5 degrees and the galactic longitude range -15 degrees < l < 255 degrees at 8.35 and 14.35 GHz were presented. These observations used the National Radio Astronomy Observatory-NASA Green Bank Earth Station to survey the sky simultaneously at these two frequencies. These GPA data are the first results from the GP Survey observations, a program to monitor this portion of the sky at 8.35 and 14.35 GHz. The GP Survey series is intended to detect short-lived radio sources. In their published paper, the authors presented four independent observations of the Galactic plane, combined to provide a set of reference images of the Galactic plane. This first GPA survey covers 0.82 steradian (6.5%) of the sky. This table conatins a source list of all sources which were brighter than 0.9 Jy at 8.35 GHz and also of 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 at <a href="http://www.gb.nrao.edu/~glangsto/GPA">http://www.gb.nrao.edu/~glangsto/GPA</a> .
