Class lsst::jointcal::ConstrainedAstrometryModel

class ConstrainedAstrometryModel : public lsst::jointcal::AstrometryModel

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.

Parameters

• 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.
