Implementation ticket for RFC-545.
Once PhotoCalib replaces Calib (
DM-10153), we will set a config parameter in AssembleCoaddTask to allow disabling ScaleZeroPointTask and mark it deprecated. We can then test whether we think we still need it by disabling it and processing some HSC data.
Now that PhotoCalib is defined in nanojansky, the resulting warps will have "human understandable" calibrated fluxes, without having the mean calibration divided out.
