ATNF psrcat v1.70 includes dcm+23 -- https://ui.adsabs.harvard.edu/abs/2022arXiv221009172D/abstract   The second set of pulsar discoveries by CHIME/FRB/Pulsar: 14 Rotating Radio Transients and 7 pulsars  Dong, Fengqiu Adam ; Crowter, Kathryn ; Meyers, Bradley W. ; Pleunis, Ziggy ; Stairs, Ingrid ; Tan, Chia Min ; Yu, Tinyau Timothy ; Boyle, Patrick J. ; Cook, Amanda M. ; Fonseca, Emmanuel ; Gaensler, Bryan M. ; Good, Deborah C. ; Kaspi, Victoria ; McKee, James W. ; Patel, Chitrang ; Pearlman, Aaron B. 

We noticed that the position of PSR J2116+3701 closely matches that of the 4FGL source listed above and on the SED below, where 4FGL is the Incremental Fermi Large Area Telescope Fourth Source Catalog  Abdollahi, S. et al. 2022, ApJS, 260, 53   doi: 10.3847/1538-4365/ac6751  arXiv: 2201. 11184     ADS: 2022ApJS..260...53A    

That source is non-variable (unlike many pulsarsmost blazars) and has the pulsar-like SED shown below.:

From the Table in dcm+23 we created J2116+3701.par and we gamma-ray phase-folded the Fermi LAT data using the methods described in Searching a Thousand Radio Pulsars for Gamma-ray Emission Smith, D. A. et al. 2019ApJ...871...78S . We thank dcm+23 lead author Fengqiu Adam Dong for having sent us the .par, the radio pulse profile to overlay on the gamma-ray phase histogram, and for other useful exchanges. This first folding gave an Htest of 66 for >14 years of LAT data, with a peak near 160 about 2000 days before the beginning of the radio ephemeris validity.
