Detailed Description

A shape pseudo-algorithm for forced measurement that simply transforms the shape
from the reference catalog to the measurement coordinate system.  This is used as
the slot shape by default in forced measurement, allowing subsequent measurements
to simply refer to the slot value just as they would in single-frame measurement.

Member Function Documentation

◆ fail()

def lsst.meas.base.pluginsBase.BasePlugin.fail (   self,
  measRecord,
  error = None 
)
inherited

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.

◆ getTransformClass()

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

Get the measurement transformation appropriate to this plugin.

This returns a subclass of 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.

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

◆ measureN()

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