Abstract
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 degrees in the Taylor et al. catalog. We have identified 79 sour ces stronger than similar to 2.5 mJy as pulsars through positional coi ncidence. Fifteen of these pulsars were also identified with sources i n the 325 MHz Westerbork Northern Sky Survey (WENSS). Our sample is fr ee from period and dispersion selection effects beyond those of the or iginal catalog, and we have attempted to characterize the effects of i nterstellar scintillation on the source flux densities reported by NVS S. 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 s cintillation are quite accurate and may be used to calibrate future ob servations.
