Notes. For all details on the data reduction, see Kiss et al. (2014). The photometric uncertainty is derived from aperture photometry on 200 artificial sources, resembling the PACS PSF in the respective band, that have been planted individually on the double-differential image. The distribution of measured artificial source fluxes resembles a Gaussian, so its standard deviation defines the photometric uncertainty of the respective image. λ_ref – reference wavelength for respective band, r_H – heliocentric distance at mid-time, Δ – Herschel-centric distance at mid-time, α – phase angle at mid-time, FD – color-corrected monochromatic flux density at reference wavelength, 1σ – estimated uncertainty of FD (includes the 5% absolute flux calibration error of PACS).
