Detailed Description

An abstract base classes for which the same implementation can be used for both SingleFrameAlgorithm and ForcedAlgorithm.

SimpleAlgorithm allows a ForcedAlgorithm to be defined using the measure() and measureN() signatures of SingleFrameAlgorithm. It should be used for any algorithm for which the forced version of the algorithm does not require anything to be transformed beyond the centroid and shape, and for which the the parameters being fit are the same for both single-frame and forced measurement. This should be the case for all flux algorithms that don't involve fitting any additional model parameters. It can also be used for centroid and shape algorithms, where having a version that can re-measure values in forced mode may be useful for diagnostic purposes even if it is not useful for science.

inlinevirtual

Called to measure a single child source in an image.

Before this method is called, all neighbors will be replaced with noise, using the outputs of the deblender. Outputs should be saved in the given SourceRecord, which can also be used to obtain centroid (see SafeCentroidExtractor) and shape (see SafeShapeExtractor) information.

Implements lsst::meas::base::ForcedAlgorithm.

         measure(measRecord, exposure);

		afw::image::Exposure< float > const &	exposure,
		afw::table::SourceCatalog const &	refRecord,
		afw::image::Wcs const &	refWcs
	)		const

inlinevirtual

Called to simultaneously measure all children in a deblend family, in a single image.

Outputs should be saved in the given SourceCatalog, which can also be used to obtain centroid (see SafeCentroidExtractor) and shape (see SafeShapeExtractor) information.

The default implementation simply throws an exception, indicating that simultaneous measurement is not supported.

Reimplemented from lsst::meas::base::ForcedAlgorithm.

         measureN(measCat, exposure);
