The image is a map of the entire sky at the radio wavelength of 21-cm (or 1420 MHz radio frequency). The data is from the 21-cm maps presented by Dickey and Lockman in the Annual Review of Astronomy and Astrophyscs, 1990, Vol. 28, p215. The brightest radio sources are marked. These are the sources that are easily detected with the SGRA 4.6-m radio telescope.
