The forced peak centroid is like the SFM peak centroid plugin, except that it must transform
the peak coordinate from the original (reference) coordinate system to the coordinate system
of the exposure being measured.

Record a failure of the measure or measureN() method.
When the plugin raises an exception, framework will call fail() to allow the plugin to set its failure flag field(s). When measureN() raises an exception, fail() will be called repeatedly with all the records that were being measured.
If the exception is a 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.

Measure the properties of a group of blended sources on a single image,
given data from a reference record.
@param[in] exposure lsst.afw.image.ExposureF, containing the pixel data to
be measured and the associated Psf, Wcs, etc. Sources
not in the blended hierarchy to be measured will have
been replaced with noise using deblender outputs.
@param[in,out] measCat lsst.afw.table.SourceCatalog to be filled with outputs,
and from which previously-measured quantities can be
retrieved, containing only the sources that should be
measured together in this call.
@param[in] refCat lsst.afw.table.SimpleCatalog that contains additional
parameters to define the fit, as measured elsewhere.
Ordered such that zip(sources, references) may be used.
@param[in] refWcs The coordinate system for the reference catalog values.
An afw.geom.Angle may be passed, indicating that a
local tangent Wcs should be created for each object
using afw.image.makeLocalWcs and the given Angle as
a pixel scale.
In the normal mode of operation, the source centroids 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.
