This is the model used to fit mappings as the combination of a transformation depending on the chip number (instrument model) and a transformation per visit (anamorphism).
The two-transformation Mapping required for this model is ChipVisitAstrometryMapping. This modeling of distortions is meant for a set of images from a single mosaic imager.

Positions the various parameter sets into the parameter vector, starting at firstIndex.
This routine decodes "DistortionsChip" and "DistortionsVisit" in whatToFit.
If whatToFit contains "Distortions" and not Distortions<Something>, it is understood as both chips and visits.
