81 This class simply provides __init__ and measure methods that matched the ForcedPlugin signatures
82 and delegate to CModelAlgorithm implementations.
84 The CModel algorithm currently cannot be run in forced mode when the measurement WCS is different
85 from the reference WCS (as is the case in CCD forced photometry). This is a temporary limitation
86 that will be addressed on DM-5405.
88 CModel forced measurement when the measurement image is the same as the reference image should be
89 almost -- but not quite -- identical to unforced measurement. The primary difference is that
90 the final fit region from the reference measurement will be used for the initial fit in forced mode
91 as well as the exp, dev, and combined exp+dev fits
