There are actually two problems:
  1. SWarp (and other AstrOmatic software) only support the PC parameters using the obsoleted PC00i00j syntax, not the more recent, official, PCi_j's
  2. PC keywords provided in the coadd.head "output" headers would be ignored since pre-defined CDi_j keywords would already be there, and those have precedence in SWarp.

This should be fixed in SWarp 2.37 (r134):
  • Both PC00i00j 's and PCi_j 's are now supported,
  • If PC00i00j 's and PCi_j 's are found in external .head files, pre-existing CDi_j 's are now automatically removed, and vice versa.
    Tests done with the new version and the headers provided by jeffreyrdcs now give correct results. Other AstrOmatic packages will be updated later on to reflect those changes.
