Detailed Description

A subtask for measuring the properties of sources on a single exposure.

Parameters
----------
schema : `lsst.afw.table.Schema`
    Schema of the output resultant catalog. Will be updated to provide
    fields to accept the outputs of plugins which will be executed by this
    task.
algMetadata : `lsst.daf.base.PropertyList`, optional
    Used to record metadaa about algorithm execution. An empty
    `lsst.daf.base.PropertyList` will be created if `None`.
**kwds
    Keyword arguments forwarded to `BaseMeasurementTask`.

Member Function Documentation

◆ callMeasure()

def lsst.meas.base.baseMeasurement.BaseMeasurementTask.callMeasure	(		self,
			measRecord,
		*	args,
		**	kwds
	)

inherited

Call ``measure`` on all plugins and consistently handle exceptions.

Parameters
----------
measRecord : `lsst.afw.table.SourceRecord`
    The record corresponding to the object being measured. Will be
    updated in-place with the results of measurement.
*args
    Positional arguments forwarded to ``plugin.measure``
**kwds
    Keyword arguments. Two are handled locally:

    beginOrder : `int`
        Beginning execution order (inclusive). Measurements with
        ``executionOrder`` < ``beginOrder`` are not executed. `None`
        for no limit.

    endOrder : `int`
        Ending execution order (exclusive). Measurements with
        ``executionOrder`` >= ``endOrder`` are not executed. `None`
        for no limit.

    Others are forwarded to ``plugin.measure()``.

Notes
-----
This method can be used with plugins that have different signatures;
the only requirement is that ``measRecord`` be the first argument.
Subsequent positional arguments and keyword arguments are forwarded
directly to the plugin.

This method should be considered "protected": it is intended for use by
derived classes, not users.

Call the configured measument plugins on an image.

Parameters
----------
noiseReplacer : `NoiseReplacer`
    Used to fill sources not being measured with noise.
measCat : `lsst.afw.table.SourceCatalog`
    Catalog to be filled with the results of measurement. Must contain
    all the `lsst.afw.table.SourceRecord`\ s to be measured (with
    `lsst.afw.detection.Footprint`\ s attached), and have a schema
    that is a superset of ``self.schema``.
exposure : `lsst.afw.image.ExposureF`
    Image containing the pixel data to be measured together with
    associated PSF, WCS, etc.
beginOrder : `float`, optional
    Start execution order (inclusive): measurements with
    ``executionOrder < beginOrder`` are not executed. `None` for no
    limit.
endOrder : `float`, optional
    Final execution order (exclusive): measurements with
    ``executionOrder >= endOrder`` are not executed. `None` for no
    limit.
