Detailed Description

Evaluate the local value of the Photometric Calibration in the exposure.

The aim is to store the local calib value within the catalog for later
use in the Science Data Model functors.

Constructor & Destructor Documentation

__init__()

			config,
			name,
			schema,
			metadata )

Member Function Documentation

fail()

lsst.meas.base.wrappers.GenericPlugin.fail ( self, measRecord, error = None )

inherited

Record a measurement failure.

This default implementation simply records the failure in the source
record.

Parameters
----------
measRecord : `lsst.afw.table.SourceRecord`
    Catalog record for the source being measured.
error : `Exception`
    Error causing failure, or `None`.

Reimplemented from lsst.meas.base.pluginsBase.BasePlugin.

Reimplemented in lsst.meas.base.plugins.InputCountPlugin, and lsst.meas.base.plugins.VariancePlugin.

Definition at line 595 of file wrappers.py.

getExecutionOrder()

lsst.meas.base.plugins.EvaluateLocalPhotoCalibPlugin.getExecutionOrder

(

cls

)

Get the relative execution order of this plugin.

Must be reimplemented as a class method by concrete derived classes.

Reimplemented from lsst.meas.base.wrappers.GenericPlugin.

Definition at line 423 of file plugins.py.

getLogName()

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

inherited

Definition at line 134 of file pluginsBase.py.

getTransformClass()

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.

Definition at line 169 of file pluginsBase.py.

makeForcedPlugin()

lsst.meas.base.wrappers.GenericPlugin.makeForcedPlugin ( cls, name )

inherited

Produce a ForcedPlugin subclass from this GenericPlugin class.

The class is also registered.

Parameters
----------
name : `str`
    Name of plugin to register.

Definition at line 652 of file wrappers.py.

makeSingleFramePlugin()

lsst.meas.base.wrappers.GenericPlugin.makeSingleFramePlugin ( cls, name )

inherited

Produce a SingleFramePlugin subclass from this GenericPlugin class.

The class is also registered.

Parameters
----------
name : `str`
    Name of plugin to register.

Definition at line 611 of file wrappers.py.

measure()

lsst.meas.base.plugins.EvaluateLocalPhotoCalibPlugin.measure	(		self,
			measRecord,
			exposure,
			center )

Measure a single source.

It is the responsibility of this method to perform the desired
measurement and record the result in the `measRecord`.

Parameters
----------
measRecord : `lsst.afw.table.SourceRecord`
    Catalog record for the source being measured.
exposure : `lsst.afw.image.Exposure`
    Exposure on which the source is being measured.
center : `lsst.geom.Point2D`
    Pixel coordinates of the object.

Raises
------
MeasurementError
    Raised if the measurement fails for a known/justifiable reason.

Reimplemented from lsst.meas.base.wrappers.GenericPlugin.

Definition at line 439 of file plugins.py.

measureN()

lsst.meas.base.wrappers.GenericPlugin.measureN ( self, measCat, exposure, refCat, refWcs )

inherited

Measure multiple sources.

It is the responsibility of this method to perform the desired
measurement and record the result in the `measCat`.

Parameters
----------
measCat : `lsst.afw.table.SourceCatalog`
    Catalog for the sources being measured.
exposure : `lsst.afw.image.Exposure`
    Exposure on which the source is being measured.
refCat : `lsst.afw.table.SourceCatalog`
    Reference catalog.
refWcs : `lsst.afw.image.Wcs`
    Astrometric solution for the reference image.

Raises
------
MeasurementError
    Raised if the measurement fails for a known/justifiable reason.

Definition at line 571 of file wrappers.py.
