\========= NIKA2_fidcc_powerlaw.xcat
\------------------------------------------------------------------
\========= This file contains fiducial color corrections for a power law spectrum and the NIKA2 filters
\========= It is used to quantify the accuracy of the NIKA2 color corrections implemented in DustEMWrap
\========= Undefined/unknown values set to -32768
\========= Fiducial values from Perotto et al (2020)
\========= Column keys:
\========= alpha: power law index, i.e. Fnu \propto nu^alpha
\========= Subsequent columns have the (DustEMWrap-default) filter names
\========= FILTER REFWAVE (mu)
\========= NIKA21 1153.04789 (260GHz, avg of A1 and A3)
\========= NIKA22 1998.61648 (150GHz, A2)
