Detailed Description

Base class for measurement plugins.

This is the base class for `SingleFramePlugin` and `ForcedPlugin`; derived
classes should inherit from one of those.

Parameters
----------
config : `BasePluginConfig`
    Plugin configuration.
name : `str`
    Plugin name.
logName : `str`
    Logger name.

Notes
-----
Relative execution orders are defined by a series of named constants
defined in this class: plugins with a lower execution number are run
first.

This approach was chosen instead of a full graph-based analysis of
dependencies because algorithm dependencies are usually both quite simple
and entirely substitutable: an algorithm that requires a centroid can
typically make use of any centroid algorithms outputs.  That makes it
relatively easy to figure out the correct value to use for any particular
algorithm.

Constructor & Destructor Documentation

◆ init()

lsst.meas.base.pluginsBase.BasePlugin.__init__	(	self,
		config,
		name,
		logName = None )

Definition at line 128 of file pluginsBase.py.

    def __init__(self, config, name, logName=None):
        object.__init__(self)
        self.config = config
        self.name = name
        self.logName = logName
 

Member Function Documentation

◆ fail()

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

Record a failure of the `measure` or `measureN` method.

Parameters
----------
measRecord : `lsst.afw.table.SourceRecord`
    Table record describing the source being measured.
error : `MeasurementError`, optional
    Only provided if the measurement failed due to a
    `MeasurementError` being raised; otherwise, will be `None`.

Notes
-----
When the plugin raises an exception, framework will call
`BasePlugin.fail` to allow the plugin to set its failure flag
field(s).  When `BasePlugin.measureN` raises an exception,
`BasePlugin.fail` will be called repeatedly with all the records that
were being measured.

If the exception is an `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.

◆ getExecutionOrder()

◆ getTransformClass()

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

static

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.SingleFramePeakCentroidPlugin, and lsst.meas.base.plugins.ForcedPeakCentroidPlugin.
