IPs Sorted by Swift/BAT 14-195 keV Fluxes

The table below lists 43 of the 71 confirmed/ironclad IPs from the 2021 version of the IP catalog in the order of their 14-195 keV fluxes (in the unit of 10^-12 ergs cm^-2s^-1) as listed in the Swift BAT 157-month survey.

One object, RX J2015.6+3711, is one of the two counterparts of the BAT source, Swift J2015.9+3715 and therefore is not included in this table. The remaining 27 objects are not known to be BAT sources.
