      Description

      The P2 "Principal Color" coeffecients à la Ivezić et al. 2004 (2004AN....325..583I) have been derived for the HSC filters (see DM-13154, DM-13651, DM-13519). The final, P2', principal color (for the gri filters) in Ivezić et al. 2004 also includes a slight dependence of P2 vs. r band mag observed in the SDSS data: see Fig 2 and Section 3.2.1 of Ivezić et al. 2004. Investigate if such an additional calibration is required for the HSC data. Note that any observed correlation with magnitude may depend on the magnitude threshold used in fitting the original P2 coefficients, so this should be done in conjunction with the findings of DM-14196.
