Source_Name
0FGL JHHMM.m+DDMM, constructed according to IAU Specifications for Nomenclature; m is decimal minutes of R.A.; in the name R.A. and decl. are truncated at 0.1 decimal minutes and 1' , respectively
Right Ascension, J2000, deg, 3 decimal places
Declination, J2000, deg, 3 decimal places
Galactic Longitude, deg, 3 decimal places
Galactic Latitude, deg, 3 decimal places
Radius of 95% confidence region, deg, 3 decimal places
Square root of likelihood TS from 200 MeV - 100 GeV analysis, used for the TS > 100 cut, 1 decimal place
Flux 100 MeV to 1 GeV (i.e., log_10 E = 2-3), 10^-8 cm^-2 s^-1, 2 decimal places
1 sigma uncertainty on F_23, same units and precision. A 0 in this column indicates that the entry in the F_23 flux column is an upper limit.
Flux for 1 GeV to 100 GeV (i.e., log_10 E = 3-5), 10^-8 cm^-2 s^-1, 2 decimal places
1 sigma uncertainty on F_35, same units and precision.
T indicates < 1% chance of being a steady source on a weekly timescale
Square root of TS for the 100 MeV to 1 GeV range, 1 decimal place
Square root of TS for the 1 GeV to 100 GeV range, 1 decimal place
Identification or positional associations with 3EG, EGR, or AGILE sources
Identification or positional associations with 3EG, EGR, or AGILE sources
Identification or positional associations with 3EG, EGR, or AGILE sources
Class designation for associated source. Capital letters indicate firm identifications; lower-case letters indicate associations: Pulsar (PSR), Pulsar wind nebula (pwn), High-mass X-ray binary (hxb), BL Lac type of blazar (bzb), FSRQ type of blazar (bzq), Uncertain type of blazar (bzu), Radio galaxy (rdg), Globular cluster (glb), Special case - potential association with SNR or PWN (x), Unassociated ( ).
