Gamma-ray observations of low-luminosity active galactic nuclei

Data generated from the paper De Menezes et al. 2020, "Gamma-ray observations of low-luminosity active galactic nuclei" published in MNRAS (DOI:10.1093/mnras/staa083). This dataset includes the following files:

1. all figures from the paper
2. results of spectral fits to the Fermi LAT emission from low-luminosity AGNs (LLAGNs) in the Palomar sample (``)
3. TS maps: FITS files with all TS maps (``) and image combining all TS maps (`all-ts-maps.png`)
4. ASCII file with the luminosities in radio, gamma-rays and X-rays (`data_Gamma-Radio-X.dat`)
5. full spectral energy distribution (SEDs) for NGC 315 and NGC 4261, including RIAF and SSC model data

More information about each of the data products above are included below. This text is also included in the file `` included.

# 1. Figures from paper

All the plots included in the latest version of the paper are included in the repository in the PNG format. Some of the figures are in the zip files.

# 2. Spectral fits to the globular clusters *Fermi* LAT emission

The file `` includes ASCII files with the output from the spectral fits performed to each of the 197 LLAGNs analysed, such as

- flux
- spectrum type
- prefactor
- index

The modelling was carried out with ScienceTools v1.0.0 and fermipy v0.17.4.

# 3. FITS files with the TS maps for all sources

The file `` includes FITS files with the images for the TS maps generated for the field of each LLAGN.

The value of TS corresponds roughly to the square of the statistical significance of the presence of a point source above background, in standard deviations. As such, a value of TS=25 would correspond to a source detected at ~5sigma.
