AGILE–GRID second catalogue column descriptions of Tables 10, 13, and 14.
| Column | Units | Description |
|---|---|---|
| Name | 2AGL JHHMM+DDMM[c/e] constructed according to IAU Specifications for Nomenclature; in the name, RA and Decl. are truncated at 0.1′ and 1′, respectively; “c” indicates that based on the region of the sky the source is potentially confused with Galactic diffuse emission; “e” indicates a source modelled as spatially extended | |
| RA | deg | Right Ascension, J2000 |
| Dec | deg | Declination, J2000 |
| l | deg | Galactic Longitude |
| b | deg | Galactic Latitude |
| r | deg | Radius of 95% c.l. circular confidence region, deg. Statistical error only |
| θa | deg | Semi-major axis of 95% c.l. elliptical confidence region, deg. Statistical error only |
| θb | deg | Semi-minor axis of 95% c.l. elliptical confidence region, deg. Statistical error only |
| ϕ | deg | Position angle of 95% confidence region, clockwise |
| SM | Spectral model. PL indicates power-law fit to the energy spectrum; PC indicates power-law with exponential cut-off fit to the energy spectrum; PS indicates power-law with super exponential cut-off fit to the energy spectrum; LP indicates log-parabola fit to the energy spectrum | |
 |
Significance derived from likelihood test statistic in the energy range 100 MeV–10 GeV | |
| α | Spectral index for PL, PC, and PS spectral models, first index for LP spectral model, in the energy range 100 MeV–10 GeV; see Sect. 4.1.2 for the definition of α | |
| Δα | Statistical 1σ uncertainty of α, in the energy range 100 MeV–10 GeV | |
| Fγ | 10−8 ph cm−2 s−1 | Photon flux in the energy range 100 MeV–10 GeV, summed over 4 bands, for the pointing mode period |
| δFγ | 10−8 ph cm−2 s−1 | Statistical 1σ uncertainty of Fγ |
| Fe | 10−9 erg cm−2 s−1 | Integrated energy flux in the energy range 100 MeV–10 GeV, for the pointing mode period |
| δFe | 10−9 erg cm−2 s−1 | Statistical 1σ uncertainty of Fe |
| VI | Variability index equal to 1 indicates <1% chance of being a steady source. No value indicates that there are not enough 4 day time periods to calculate the index. See Sect. 4.8 for more details. | |
| Exp | cm2 Ms [days] | Exposure in cm2 Ms and days. Days are obtained dividing exposure by the mean Aeff = 300 cm2 and 86 400 s |
| Flag | Flag (see Table 2) | |
| AGL assoc. | Positional associations with sources from AGILE catalogues listed in Table 6. For AGILE–TeVCat we added the AGL prefix to the catalogue name | |
| γ-ray assoc. | Positional associations with sources not from AGILE catalogues listed in Table 6. For the same source in the FGL catalogues, we kept the association with the last FGL catalogue | |
| ID or assoc. | Designator of identified or associated source, A * indicates a possible marginal positional association | |
| Class | Class (see Table 5) |
