Geminga field at 74 MHz. The 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 ﹩24\farcs 6\times 23\farcs 3﹩ at a position angle of 64°, and the rms noise level is 28 mJy beam−1. Contour levels are 28 mJy beam−1 × −2, 2, 3, 5. Also indicated are two sources from the NRAO VLA Sky Survey (Condon et al. 1998).
