ConfigClass = GeneralShapeletPsfApproxForcedConfig | |
Minimal subclass of GeneralShapeletPsfApproxMixin to conform to the forced measurement API. This class simply provides __init__ and measure methods that matched the ForcedPlugin signatures and delegate to the GeneralShapeletPsfApproxMixin's implementations.

lsst.meas.modelfit.psf.psfContinued.GeneralShapeletPsfApproxForcedPlugin.fail | ( | self, | |
measRecord, | |||
error = None ) |
Record a failure of the `measure` or `measureN` method. Parameters ---------- measRecord : `lsst.afw.table.SourceRecord` Table record describing the source being measured. error : `MeasurementError`, optional Only provided if the measurement failed due to a `MeasurementError` being raised; otherwise, will be `None`. Notes ----- When the plugin raises an exception, framework will call `BasePlugin.fail` to allow the plugin to set its failure flag field(s). When `BasePlugin.measureN` raises an exception, `BasePlugin.fail` will be called repeatedly with all the records that were being measured. If the exception is an `MeasurementError`, it will be passed as the error argument; in all other cases the error argument will be `None`, and the failure will be logged by the measurement framework as a warning.

Get the relative execution order of this plugin. Must be reimplemented as a class method by concrete derived classes.

refWcs ) |
Measure the properties of a source given an image and a reference. Parameters ---------- exposure : `lsst.afw.image.ExposureF` The pixel data to be measured, together with the associated PSF, WCS, etc. All other sources in the image should have been replaced by noise according to deblender outputs. measRecord : `lsst.afw.table.SourceRecord` Record describing the object being measured. Previously-measured quantities will be retrieved from here, and it will be updated in-place with the outputs of this plugin. refRecord : `lsst.afw.table.SimpleRecord` Additional parameters to define the fit, as measured elsewhere. refWcs : `lsst.afw.geom.SkyWcs` or `lsst.afw.geom.Angle` The coordinate system for the reference catalog values. An `~lsst.geom.Angle` may be passed, indicating that a local tangent WCS should be created for each object using the given angle as a pixel scale. Notes ----- In the normal mode of operation, the source centroid will be set to the WCS-transformed position of the reference object, so plugins that only require a reference position should not have to access the reference object at all.
