| ConfigClass = ForcedTransformedCentroidConfig | |
Record the transformation of the reference catalog centroid.
The centroid recorded in the reference catalog is tranformed to the
measurement coordinate system and stored.
Parameters
----------
config : `ForcedTransformedCentroidConfig`
Plugin configuration
name : `str`
Plugin name
schemaMapper : `lsst.afw.table.SchemaMapper`
A mapping from reference catalog fields to output
catalog fields. Output fields are added to the output schema.
metadata : `lsst.daf.base.PropertySet`
Plugin metadata that will be attached to the output catalog.
Notes
-----
This is used as the slot centroid by default in forced measurement,
allowing subsequent measurements to simply refer to the slot value just as
they would in single-frame measurement.

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

| measRecord, | |||
| exposure, | |||
| refRecord, | |||
| 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 All other sources in the image should have been replaced
by noise according to deblender outputs.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.
