A Population-Informed Mass Estimate for Pulsar J0740+6620
  Galactic double neutron star systems have a tight mass distribution around
$\sim 1.35 M_{\odot}$, but the mass distribution of all known pulsars is
broader. Here we reconstruct the Alsing, et al. (2018) bimodal mass
distribution of pulsars observed in binary systems, incorporating data from
observations of J0740+6620 which were not available at the time of that work.
Because J0740+6620 is an outlier in the mass distribution with non-negligible
uncertainty in its mass measurement, its mass receives a large correction from
the population, becoming $m_{J0740+6620} = 2.03^{+0.10}_{-0.08} \, M_\odot$
(median and 68\% CI). Stochastic samples from our population model, including
population-informed pulsar mass estimates, are available at
