*Red entries are triggered by abs(entry) > (0.02 0.02 0.02 0.02 0.03) in (u g r i z)
The table above lists the photometric zeropoint corrections
required for a flat background across all camera columns.

*Red entries are triggered by abs(entry) > (0.02 0.02 0.02 0.02 0.03) in (u g r i z)
The table above lists the photometric zeropoint corrections
required to make the median principal colors (for all fields in
a camera column) to be 0 (assuming that errors in gri add up to 0)
