Fig. 2
The spectrum of the Crab pulsar in the 110–200 MHz range. Solid triangles represent flux densities at 111.5 and 196.5 MHz, respectively (Vandenberg et al. 1973). Flux density at 121.6 MHz (shown using filled square) comes from Erickson et al. (1972). Open circles are fluxes derived from observing session III of the present work. The error bars on the open circles correspond to 20% uncertainty in the flux measurements.
