Implementation of the Photometric Calibration class.
A class to contain the data, WCS, and other information needed to describe an image of the sky.
Definition Exposure.h:72
An affine coordinate transformation consisting of a linear transformation and an offset.
Point in an unspecified spherical coordinate system.
Definition SpherePoint.h:57
double Scalar
Typedefs to be used for probability and parameter values.
Definition common.h:44
A local mapping between two UnitSystems.
Definition UnitSystem.h:80
double flux
Multiply source fluxes by this to get destination fluxes.
Definition UnitSystem.h:85
LocalUnitTransform(geom::Point2D const &sourcePixel, UnitSystem const &source, UnitSystem const &destination)
geom::AffineTransform geometric
Maps source pixel coordinates to destination pixel coordinates.
Definition UnitSystem.h:82
