◆ calculate() [1/2]

def lsst.meas.base.catalogCalculation.CatalogCalculationPlugin.calculate	(		self,
			cat,
		**	kwargs
	)

inherited

Perform the calculation specified by this plugin.

This method can either be used to operate on a single catalog record
or a whole catalog, populating it with the output defined by this
plugin.

Note that results may be added to catalog records as new columns, or
may result in changes to existing values.

Parameters
----------
cat : `lsst.afw.table.SourceCatalog` or `lsst.afw.table.SourceRecord`
    May either be a `~lsst.afw.table.SourceCatalog` or a single
    `~lsst.afw.table.SourceRecord`, depending on the plugin type. Will
    be updated in place to contain the results of plugin execution.
**kwargs
    Any additional keyword arguments that may be passed to the plugin.

Compute the sigma fluxes of the point source flux measured on the
calibrated image.

Parameters
----------

◆ fail() [2/2]

def lsst.meas.base.pluginsBase.BasePlugin.fail	(	self,

inherited

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()

def lsst.meas.base.diaCalculationPlugins.SigmaDiaTotFlux.getExecutionOrder ( cls )

Used to set the relative order of plugin execution.

The values returned by `getExecutionOrder` are compared across all
plugins, and smaller numbers run first.

Notes
-----
`CatalogCalculationPlugin`\s must run with
`BasePlugin.DEFAULT_CATALOGCALCULATION` or higher.

All plugins must implement this method with an appropriate run level

◆ getTransformClass()

def 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.
