Issue DM-3265: add task to meas_astrom to fit an aribtrary WCS with a TAN-SIP WCS
Sometime in the past, Russell Owen wrote a method to take an arbitrary WCS and approximate it as a TanWcs (our implementation of FITS' TAN-SIP WCS formalism). That method is currently just a utility function in the unit test testFitTanSipWcsHighOrder.py. This issue will promote that method to a full-fledge task in meas_astrom.
