A multi-component model, fitting mappings for sensors and visits simultaneously.
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.
ccdImageList | The exposures that will be fit. |
projectionHandler | The projection from "Sky" (where the "true" coordinates live) to "Tangent Plane" (where the fitting occurs). |
chipOrder | The polynomial order of the pixel->focal plane mapping for each sensor. |
visitOrder | The polynomial order of the focal plane->tangent plane mapping for each visit. |

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.
