Abstract:
We study the correlation between gamma-ray and radio band radiation
for 123 blazars, using the Fermi-LAT first source catalog (1FGL) and
the RATAN-600 data obtained at the same period of time (within a few
months).
Description:
For the correlation analysis, we cross-match the first Fermi-LAT
catalogue (1FGL) with the RATAN-600 observations. The 1FGL catalogue
is available in the Vizier data base and its description is given in
Abdo et al. (2010, Cat. J/ApJ/715/429). The catalogue includes
observational data obtained during the period from 2008 August 4 to
2009 July 4 for 1451 AGNs and contains information for five gamma-ray
bands: 0.1-0.3, 0.3-1, 1-3, 3-10 and 10-100GeV. Gamma-ray
flux units are photons per second per square centimetre (ph/cm2/s).
The counts in each band are averaged over 11 months.
About 300 AGNs were observed with the RATAN-600 radio telescope within
a few months of the Fermi-LAT observations, as part of various
programmes. For the analysis, we used flux densities measured at five
frequencies (2.3, 4.8, 7.7, 11.2 and 21.7GHz) in 2008 November and
2009 April. Each source was observed five to 10 times during this
period.
We list the radio flux densities at five frequencies: 2.3, 4.8, 7.7,
11.2 and 21.7GHz, used in this work, along with the spectral index
values, measured between 2.3 and 7.7GHz, but for two sources measured
between 4.8 and 7.7GHz due to the absence of observations at 2.3GHz
for them).
