A measurement algorithm that estimates flux using an elliptical Gaussian weight.
This algorithm computes flux as the dot product of an elliptical Gaussian weight function with the image. The size and ellipticity of the weight function are determined using the SdssShape algorithm, or retreived from a named field.

Handle an exception thrown by the current algorithm by setting flags in the given record.
fail() is called by the measurement framework when an exception is allowed to propagate out of one the algorithm's measure() methods. It should generally set both a general failure flag for the algorithm as well as a specific flag indicating the error condition, if possible. To aid in this, if the exception was an instance of MeasurementError, it will be passed in, carrying information about what flag to set.
An algorithm can also to chose to set flags within its own measure() methods, and then just return, rather than throw an exception. However, fail() should be implemented even when all known failure modes do not throw exceptions, to ensure that unexpected exceptions thrown in lower-level code are properly handled.

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.

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.
