◆ fail()

def lsst.meas.base.wrappers.GenericPlugin.fail	(	self,

Record a measurement failure.

This default implementation simply records the failure in the source
record.

Parameters
----------
measRecord : `lsst.afw.table.SourceRecord`
    Catalog record for the source being measured.
error : `Exception`
    Error causing failure, or `None`.

Reimplemented from lsst.meas.base.pluginsBase.BasePlugin.

Get the relative execution order of this plugin.

Must be reimplemented as a class method by concrete derived classes.

◆ getTransformClass()

def lsst.meas.base.pluginsBase.BasePlugin.getTransformClass ( )

staticinherited

Get the measurement transformation appropriate to this plugin.

This returns a subclass of `transforms.MeasurementTransform`, which
may be instantiated with details of the algorithm configuration and
then called with information about calibration and WCS to convert from
raw measurement quantities to calibrated units. Calibrated data is
then provided in a separate output table.

Notes
-----
By default, we copy everything from the input to the output without
transformation.
