Detailed Description

Ultimate base class for all measurement tasks
other than SimpleForcedMeasurementTask.

Parameters
----------
algMetadata : `lsst.daf.base.PropertyList` or `None`
    Will be modified in-place to contain metadata about the plugins being
    run. If `None`, an empty `~lsst.daf.base.PropertyList` will be
    created.
**kwds
    Additional arguments passed to `lsst.pipe.base.Task.__init__`.

Notes
-----
This base class for `SingleFrameMeasurementTask` and
`ForcedMeasurementTask` mostly exists to share code between the two, and
generally should not be used directly.

Constructor & Destructor Documentation

◆ __init__()

lsst.meas.base.baseMeasurement.BaseMeasurementTask.__init__ ( self,
algMetadata = None,
** kwds )

Definition at line 468 of file baseMeasurement.py.

Member Function Documentation

◆ addInvalidPsfFlag()

lsst.meas.base.baseMeasurement.SimpleBaseMeasurementTask.addInvalidPsfFlag ( self,
schema )
inherited

Definition at line 326 of file baseMeasurement.py.

◆ callMeasure()

lsst.meas.base.baseMeasurement.SimpleBaseMeasurementTask.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.

Definition at line 337 of file baseMeasurement.py.

◆ doMeasurement()

lsst.meas.base.baseMeasurement.SimpleBaseMeasurementTask.doMeasurement ( self,
plugin,
measRecord,
* args,
** kwds )
inherited
Call ``measure`` on the specified plugin.

Exceptions are handled in a consistent way.

Parameters
----------
plugin : subclass of `BasePlugin`
    Plugin that will be executed.
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 forwarded to ``plugin.measure()``.

Notes
-----
This method can be used with plugins that have different signatures;
the only requirement is that ``plugin`` and ``measRecord`` be the first
two arguments.  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.

◆ getFootprintsFromCatalog()

lsst.meas.base.baseMeasurement.BaseMeasurementTask.getFootprintsFromCatalog ( catalog)
static
Get a set of footprints from a catalog, keyed by id.

Parameters
----------
catalog : `lsst.afw.table.SourceCatalog`
    Catalog with `lsst.afw.detection.Footprint`s attached.

Returns
-------
footprints : `dict` [`int`: (`int`, `lsst.afw.detection.Footprint`)]
    Dictionary of footprint, keyed by id number, with a tuple of
    the parent id and footprint.

Definition at line 487 of file baseMeasurement.py.

◆ initializePlugins()

lsst.meas.base.baseMeasurement.BaseMeasurementTask.initializePlugins ( self,
** kwds )
Initialize plugins (and slots) according to configuration.

Parameters
----------
**kwds
    Keyword arguments forwarded directly to plugin constructors.

Notes
-----
Derived class constructors should call this method to fill the
`plugins` attribute and add corresponding output fields and slot
aliases to the output schema.

In addition to the attributes added by `BaseMeasurementTask.__init__`,
a ``schema``` attribute holding the output schema must be present
before this method is called.

Keyword arguments are forwarded directly to plugin constructors,
allowing derived classes to use plugins with different signatures.

Reimplemented from lsst.meas.base.baseMeasurement.SimpleBaseMeasurementTask.

◆ initNoiseReplacer()

lsst.meas.base.baseMeasurement.BaseMeasurementTask.initNoiseReplacer ( self,
exposure,
measCat,
footprints,
exposureId = None,
noiseImage = None )
Replace all pixels in the exposure covered by the footprint of
``measRecord`` with noise.

Parameters
----------
exposure : `lsst.afw.image.Exposure`
    Exposure in which to replace pixels.
measCat : `lsst.afw.table.SourceCatalog`
    Catalog that will be measured.t
footprints : `dict` [`int`: (`int`, `lsst.afw.detection.Footprint`)]
    Dictionary of footprints, keyed by id number, with a tuple of
    the parent id and footprint.
exposureId : `int`, optional
    Unique identifier for the exposure.
noiseImage : `lsst.afw.image.Image` or `None`, optional
    Image from which to draw noise pixels.  If `None`, noise will be
    drawn from the input exposure.
