Notes.

^(a)

Estimated as the average of the rms of the relative zero point variation on the focal plane (see Appendix A).

^(b)

Number of independent determinations of the photometric correction.

^(c)

This delivers a crude estimate of the rms of residual non-uniformity in the SNLS tertiary catalogs, which are obtained by averaging over the whole survey.
