Scientific paper

The 1.4 GHz NRAO VLA Sky Survey (NVSS) was searched for phase-averaged radio emission from the 516 pulsars north of J2000 declination delta = -40 deg in the Taylor et al. catalog. We have identified 79 sources stronger than ~2.5 mJy as pulsars through positional coincidence. Fifteen of these pulsars were also identified with sources in the 325 MHz Westerbork Northern Sky Survey (WENSS). Our sample is free from period and dispersion selection effects beyond those of the original catalog, and we have attempted to characterize the effects of interstellar scintillation on the source flux densities reported by NVSS. We report spectral indices using both the WENSS 325 MHz and pulsar catalog 400 MHz flux densities. The NVSS positions may be used both to improve timing models and for VLA/VLBA phase-referencing observations. The flux densities for those pulsars not significantly affected by scintillation are quite accurate and may be used to calibrate future observations.
