Green Bank Northern Celesial Cap (GBNCC) Survey Census and Flux Density Analysis
Abstract
We have created and implemented a pipeline to search through data taken as a part of the GBNCC survey for known pulsars, returning well over 500 redetected pulsars. From these redetections, we present the measured S/N and flux density of the pulsars as well as new measurements for pulse widths and profiles. The central frequency of the GBNCC survey is 350MHz, which is low enough for markedly increased sensitivity for measurements of dispersion measure. Using the PRESTO search software, we provide new measurements of this parameter for all redetections. We utilize the measured S/Ns along with a radio frequency interference (RFI) analysis to provide a sensitivity curve and sky map for the survey, improving the precision of the expectations of the survey. Utilizing measured parameters of pulsars detected in other surveys that overlap with the GBNCC, we also shed light on the observation frequency dependence of pulsar duty cycles.
