Notes.
^a Approximate i magnitude range, when measured. For J1959, range in R.
^b 4FGL Fermi LAT 0.1-100 GeV flux in units of ${10}^{-12}\,\mathrm{erg}\,{\mathrm{cm}}^{-2}\,{{\rm{s}}}^{-1};$ double peak separation Delta_gamma (0 for single peaks).
^c J0636 timing parallax (Arzoumanian et al. 2018); all other distances are derived from the dispersion measure (DM; Yao et al. 2017).
^d From Nieder et al. (2019).
^e J0251 and J2052 values from J. S. Deneva et al. (2019, in preparation). Other values are from atnf.csiro.au/research/pulsar/psrcat/ and astro.phys.wvu.edu/GalacticMSPs.txt.
