Following the work done on
DM-20289, make the switch from the current "unity" scaling for the HSC camera focal plane to the actual physical focal plane units of millimeters (i.e. the representation preferred by the LSST stack). There are a few other packages (see list in components + fgcmcal, which doesn't seem to be recognized) that will need adjusting. The ultimate test for updates will be to run at least one full tract from the RC2 dataset (i.e. running through singleFrameDriver, skyCorrection, jointcal, coaddDriver, and multibandDriver) to make sure the results are consistent with that of the latest weekly reprocessing run.
Merging of this work will also be contingent on acceptance of an RFC to make the switch (this will be the triggered ticket for that RFC once it is written).
