Abstract
The Green Bank North Celestial Cap survey is one of the largest and most
sensitive searches for pulsars and transient radio objects. Observations for
the survey have finished; priorities have shifted toward long-term monitoring
of its discoveries. In this study, we have developed a pipeline to handle large
datasets of archival observations and connect them to recent, high-cadence
observations taken using the Canadian Hydrogen Intensity Mapping Experiment
(CHIME) telescope. This pipeline handles data for 128 pulsars and has produced
measurements of spin, positional, and orbital parameters that connect data over
observation gaps as large as 2000 days. We have also measured glitches in the
timing residuals for five of the pulsars included and proper motion for 19
sources (13 new). We include updates to orbital parameters for 19 pulsars,
including 9 previously unpublished binaries. For two of these binaries, we
provide updated measurements of post-Keplerian binary parameters, which result
in much more precise estimates of the total masses of both systems. For PSR
J0509+3801, the much improved measurement of the Einstein delay yields much
improved mass measurements for the pulsar and its companion, 1.399(6)\Msun and
1.412(6)\Msun, respectively. For this system, we have also obtained a
measurement of the orbital decay due to the emission of gravitational waves:
$\dot{P}_{\rm B} = -1.37(7)\times10^{-12}$, which is in agreement with the rate
predicted by general relativity for these masses.
