Abstract:
We present the fourth Fermi Large Area Telescope catalog (4FGL) of
γ-ray sources. Based on the first eight years of science data
from the Fermi Gamma-ray Space Telescope mission in the energy range
from 50MeV to 1TeV, it is the deepest yet in this energy range.
Relative to the 3FGL catalog, the 4FGL catalog has twice as much
exposure as well as a number of analysis improvements, including an
updated model for the Galactic diffuse γ-ray emission, and two
sets of light curves (one-year and two-month intervals). The 4FGL
catalog includes 5064 sources above 4σ significance, for which
we provide localization and spectral properties. Seventy-five sources
are modeled explicitly as spatially extended, and overall, 358 sources
are considered as identified based on angular extent, periodicity, or
correlated variability observed at other wavelengths. For 1336
sources, we have not found plausible counterparts at other
wavelengths. More than 3130 of the identified or associated sources
are active galaxies of the blazar class, and 239 are pulsars.
Description:
The analysis is based on Fermi LAT results covering the time period
August 4, 2008, to August 2, 2016 (first 8 years) in the 50MeV to 1TeV
energy range.

--------------------------------------------------------------------------------
Note (1): The coordinates are rounded, following the IAU convention. The letter
at the end can be:
c = coincident with interstellar clump,
e = extended source,
i = for Crab Nebula inverse Compton,
s = for Crab Nebula synchrotron.
Note (2): For all three spectral representations in 4FGL, the normalization
(flux density K) is defined at a reference energy E0 chosen such that
the error on K is minimal. E0 appears as Pivot_Energy in the FITS
table.
The 4FGL spectral form for FpivLP is a log-normal representation
(LogParabola) for all significantly curved spectra except pulsars, 3C
454.3 and the Small Magellanic Cloud (SMC):
Equation (2): dN/dE=K(E/E0)-α-βlog(E/E0)
The parameters K, α (spectral slope at E0), and the curvature
β appear as LPFluxDensity, LP_Index and LP_beta in the FITS
table, respectively.
Note (3): A value greater than 4 indicates significant curvature.
Note (4): The 4FGL spectral form for FpivPLEC is a subexponentially
cutoff power law for all significantly curved pulsars
(PLSuperExpCutoff):
Equation (4): dN/dE=K(E/E0)-Γexp(a(E0b-Eb))
where E0 and E in the exponential are expressed in MeV. The parameters
K, Γ (low-energy spectral slope), a (exponential factor in MeV-b),
and b (exponential index) appear as PLECFluxDensity, PLEC_Index,
PLEC_Expfactor and PLECExpIndex in the FITS table, respectively.
Note (5): Sum of 2*log(Likelihood) difference between the flux fitted in each
time interval and the average flux over the full catalog interval; a
value greater than 18.48 over 12 intervals indicates <1% chance of
being a steady source.
Note (6): Integral photon flux from 100MeV to 100GeV in each year (best fit
from likelihood analysis with spectral shape fixed to that obtained
over full interval).
Note (7): Separate 1σ errors are computed from the likelihood profile
toward lower and larger fluxes. The lower error is set equal to NULL
and the upper error is derived from a Bayesian upper limit if the 1σ
interval contains 0 (TS<1).
Note (8): Variability Index over two-month intervals; a value greater
than 72.44 over 48 intervals indicates <1% chance of being a steady source.
Note (9): Flag on TeVCat source as follows:
P = Positional association with non-extended source in TeVCat
E = Associated with an extended source in TeVCat
N = No TeV association
Note (10): Class (as in Table 7):
Designations shown in capital letters are firm identifications.
Code as follows:
PSR = Pulsar, identified by pulsations (232 occurrences)
FSRQ = FSRQ type of blazar (43 occurrences)
BLL = BL Lac type of blazar (22 occurrences)
SNR = Supernova remnant (24 occurrences)
PWN = Pulsar wind nebula (12 occurrences)
RDG = Radio galaxy (6 occurrences)
NLSY1 = Narrow-line Seyfert 1 (4 occurrences)
BCU = Blazar candidate of uncertain type (2 occurrences)
GAL = Normal galaxy (or part) (2 occurrences)
AGN = Non-blazar active galaxy (1 occurrence)
HMB = High-mass binary (5 occurrences)
LMB = Low-mass binary (1 occurrence)
BIN = Binary (1 occurrence)
NOV = Nova (1 occurrence)
SFR = Star-forming region (3 occurrences)
Designations shown in lower case letters indicate associations:
bcu = Blazar candidate of uncertain type (1310 occurrences)
bll = BL Lac type of blazar (1109 occurrences)
fsrq = FSRQ type of blazar (651 occurrences)
unk = Unknown (92 occurrences)
spp = Supernova remnant/Pulsar wind nebula (78 occurrences)
rdg = Radio galaxy (36 occurrences)
glc = Globular cluster (30 occurrences)
snr = Supernova remnant (16 occurrences)
agn = Non-blazar active galaxy (10 occurrences)
sbg = Starburst galaxy (7 occurrences)
psr = Pulsar, no pulsations seen in LAT yet (7 occurrences)
pwn = Pulsar wind nebula (6 occurrences)
nlsy1 = Narrow-line Seyfert 1 (5 occurrences)
css = Compact Steep Spectrum radio source (5 occurrences)
ssrq = Steep spectrum radio quasar (2 occurrences)
sey = Seyfert galaxy (1 occurrence)
gal = Normal galaxy (or part) (1 occurrence)
hmb = High-mass binary (3 occurrences)
lmb = Low-mass binary (1 occurrence)
Note (11): NaN in this column when ASSOC1 is defined means that the probability
could not be computed, either because the source is extended or
because the counterpart is the result of dedicated follow-up.
Note (12): Probabilities <0.8 are formally set to 0.
Note (13): For extended counterparts, this reports their extension radius.
Note (14): Each condition is indicated by one bit among the 16 bits forming
Flags. The bit is raised (set to 1) in the dubious case, so that
sources without any warning sign have Flags=0.
