TABLE PreviousNightlyZP

Contains previous nightly zeropoint coefficients of the photometric calibration.

This table contains, for every combination of detector/night/filter,
previous nightly zeropoint coefficients of the photometric calibration

Required constraints:
Primary key is (julianDayNum,filterID,deviceID,versNum)
(julianDayNum,filterID,deviceID) references DetectorSetUp(julianDayNum,filterID,deviceID)
(versNum) references PhotCalVers(versNum)
