Forced Photometry for Pan-STARRS1 Objects Based on WISE Data
R. Burenin
Abstract
We discuss the technique and results of photometric measurements based on data from the WISE infrared survey for all Pan-STARRS1 objects under the assumption that the object coordinates are known (‘‘forced’’ photometry). The photometry has been performed by taking into account a complete point spread function model and a refined background model in the WISE survey. The fluxes or upper limits on the flux in the 3.4 and 4.6 $$\mu$$ m bands have been measured for more than three billion optical objects in the northern sky at declinations $$\delta>{-}30^{\circ}$$ . These measurements will be used to identify galaxy clusters, active galactic nuclei, and quasars in the all-sky surveys of the eROSITA and Mikhail Pavlinsky ART-XC telescopes onboard the Spektr–Roentgen–Gamma space observatory.
