Class Documentation¶

class AstrometryTransformSkyWcs : public lsst::jointcal::AstrometryTransform ¶

A AstrometryTransform that holds a SkyWcs

This is intended to hold the initial estimate for the WCS. It need not be TAN-SIP, nor exactly representable as a FITS WCS.

AstrometryTransformSkyWcs does not inherit from BaseTanWcs for two reasons:

There is no need.
It is not clear how to implement all of the BaseTanWcs interface, especially corrections.

void apply(const double xIn, const double yIn, double &xOut, double &yOut) const¶

void dump(std::ostream &stream = std::cout) const¶: dumps the transform coefficients to stream.

double fit(const StarMatchList &starMatchList)¶: Not implemented; throws pex::exceptions::LogicError.
