SDSS/CFHTLS-Wide: comparison

-  SDSS/CFHTLS (i.e. CFHT-Megacam) transformations resulting from the SNLS group (Regnault et al. ):

. gCFHTLS - gSDSS = -0.156(0.002) * (g-r)SDSS

. rCFHTLS - rSDSS = -0.000(0.003) * (g-r)SDSS

. iCFHTLS - iSDSS = -0.094(0.005) * (r-i)SDSS

. zCFHTLS - zSDSS = +0.050(0.005) * (i-z)SDSS
