<--A new responsivity calibration (version) is deployed on the HCSS 7 track (this is explained in the internal report PICC-ME-TN-033 v1.01, where the associated encircled energy fraction [EEF] is given). This improves the accuracy of photometry to 3% in the blue channel and 5% in the red channel. -->

  • Point-source photometry: PACS uses 5 stars as primary calibrators with fluxes ranging from 0.6 to 15 Jy, plus fainter stars and asteroids as secondary calibrators. The absolute flux scale accuracy is dominated by the model uncertainties and amounts to 5% in the 3 filter bands. At the same time, the reproducibility for a given non-variable point source is better than 2% for all PACS bands. The flux calibration is described in detail in Balog et al, 2013, Experimental Astronomy and confirmed with asteroids in Müller et al., 2013, Experimental Astronomy.
