Geminga field at 326 MHz. A cross marks the location of the optical counterpart of Geminga (Caraveo et al. 1998); the uncertainty in the location of Geminga is approximately 100 times smaller than the size of the cross. The beam is ﹩5\farcs 0\times 4\farcs 8﹩ at a position angle of 75°, and the rms noise level is 1.4 mJy beam−1. Contour levels are 1.4 mJy beam−1 × −3, 3, 3, 5, 7.07, 10, 14.1, .... Also indicated are a number of sources from the NRAO VLA Sky Survey (Condon et al. 1998).
