namespace
lsst
Class for a simple mapping implementing a generic AstrometryTransform.
Remove all non-astronomical counts from the Chunk Exposure’s pixels.
Forward declarations for lsst::utils::Cache
For details on the Cache class, see the Cache.h file.
It uses a template rather than a pointer so that the derived classes can use the specifics of the transform. The class simplePolyMapping overloads a few routines.
A base class for image defects
Numeric constants used by the Integrate.h integrator routines.
Compute Image Statistics
- Note
Gauss-Kronrod-Patterson quadrature coefficients for use in quadpack routine qng. These coefficients were calculated with 101 decimal digit arithmetic by L. W. Fullerton, Bell Labs, Nov 1981.
- Note
The Statistics class itself can only handle lsst::afw::image::MaskedImage() types. The philosophy has been to handle other types by making them look like lsst::afw::image::MaskedImage() and reusing that code. Users should have no need to instantiate a Statistics object directly, but should use the overloaded makeStatistics() factory functions.

ConstrainedAstrometryModel
: public lsst::jointcal::AstrometryModel - #include <ConstrainedAstrometryModel.h>
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.
