Function lsst::afw::image::makePhotoCalibFromCalibZeroPoint

Function Documentation

std::shared_ptr<PhotoCalib> lsst::afw::image::makePhotoCalibFromCalibZeroPoint(double instFluxMag0, double instFluxMag0Err)

Construct a PhotoCalib from the deprecated Calib-style instFluxMag0/instFluxMag0Err values.

This provides backwards compatibility with the obsoleted Calib object that PhotoCalib replaced. It should not be used outside of tests that compare with old persisted Calib objects.

Return

Pointer to the constructed PhotoCalib.

Parameters

• instFluxMag0: The instrumental flux at zero magnitude. If 0, the resulting PhotoCalib will have infinite calibrationMean and non-finite (inf or NaN) calibrationErr.

• instFluxMag0Err: The instrumental flux at zero magnitude error. If 0, the resulting PhotoCalib will have 0 calibrationErr.
