◆ __init__()

def lsst.meas.base.wrappers.WrappedForcedPlugin.__init__ (   self,
  config,
  name,
  schemaMapper,
  metadata,
  logName = None 
)

Reimplemented from lsst.meas.base.forcedMeasurement.ForcedPlugin.

Member Function Documentation

◆ fail()

def lsst.meas.base.wrappers.WrappedForcedPlugin.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.

◆ getExecutionOrder()

def lsst.meas.base.pluginsBase.BasePlugin.getExecutionOrder (   cls)
inherited

◆ getLogName()

def lsst.meas.base.pluginsBase.BasePlugin.getLogName (   self)
inherited

Definition at line 134 of file pluginsBase.py.

◆ 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.

Reimplemented in lsst.meas.base.plugins.ForcedPeakCentroidPlugin, and lsst.meas.base.plugins.SingleFramePeakCentroidPlugin.

◆ measure()

def lsst.meas.base.wrappers.WrappedForcedPlugin.measure (   self,
  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.

Reimplemented from lsst.meas.base.forcedMeasurement.ForcedPlugin.

Definition at line 61 of file wrappers.py.

◆ measureN()

def lsst.meas.base.wrappers.WrappedForcedPlugin.measureN (   self,
  measCat,
  exposure,
  refCat,
  refWcs 
)
Measure the properties of blended sources from image & reference.

This operates on all members of a blend family at once.

Parameters
----------
exposure : `lsst.afw.image.ExposureF`
    The pixel data to be measured, together with the associated PSF,
    WCS, etc. Sources not in the blended hierarchy to be measured
    should have been replaced with noise using deblender outputs.
measCat : `lsst.afw.table.SourceCatalog`
    Catalog describing the objects (and only those objects) being
    measured. Previously-measured quantities will be retrieved from
    here, and it will be updated in-place with the outputs of this
    plugin.
refCat : `lsst.afw.table.SimpleCatalog`
    Additional parameters to define the fit, as measured elsewhere.
    Ordered such that ``zip(measCat, refcat)`` may be used.
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 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.
