Constructor & Destructor Documentation

def lsst.meas.base.forcedMeasurement.ForcedPlugin.__init__ (   self,
  config,
  name,
  schemaMapper,
  metadata,
  logName = None 
)
Initialize the measurement object.

@param[in]  config       An instance of this class's ConfigClass.
@param[in]  name         The string the plugin was registered with.
@param[in,out]  schemaMapper  A SchemaMapper that maps reference catalog fields to output
                      catalog fields.  Output fields should be added to the
                      output schema.  While most plugins will not need to map
                      fields from the reference schema, if they do so, those fields
                      will be transferred before any plugins are run.
@param[in]  metadata     Plugin metadata that will be attached to the output catalog

def lsst.meas.base.forcedMeasurement.ForcedPlugin.measure (   self,
  measRecord,
  exposure,
  refRecord,
  refWcs 
)
Measure the properties of a source 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.  All
                  other sources in the image will have been replaced by
                  noise according to deblender outputs.
@param[in,out] measRecord lsst.afw.table.SourceRecord to be filled with outputs,
                  and from which previously-measured quantities can be
                  retreived.
@param[in] refRecord      lsst.afw.table.SimpleRecord that contains additional
                  parameters to define the fit, as measured elsewhere.
@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 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.

def lsst.meas.base.forcedMeasurement.ForcedPlugin.measureN (   self,
  measCat,
  exposure,
  refCat,
  refWcs 
)
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.
