The two high latitude COS-B γ-ray sources observed by SAS-2 in the >100 MeV energy range

The two sources with high galactic latitudes detected by the COS-B detector, namely 3C273 and 2CG 010-31, have been studied with the SAS-2 data by using the cross-correlation function method. It has been found that both of them have a corresponding γ-ray peak in the SAS-2 correlated flux. The flux values derived are in good agreement with previous results. These indicate that it is consistently appropriate to apply the cross-correlation function method to the SAS-2 data and that fruitful results are available from the analysis of the SAS-2 data.
