Detailed Description

Task to measure the normalized calibration flux.

Parameters
----------
schema : `lsst.afw.table.Schema`
    Schema for the input table; will be modified in place.
**kwargs : `dict`
    Additional kwargs to pass to lsst.pipe.base.Task.__init__()

Raises
------
NormalizedCalibrationFluxError
    Raised if there are not enough sources to calculate normalization.

Member Function Documentation

◆ _measure_aperture_correction()

lsst.meas.algorithms.normalizedCalibrationFlux.NormalizedCalibrationFluxTask._measure_aperture_correction	(	self,
		exposure,
		catalog )

protected

Internal method to do the aperture correction measurement.

This measures the aperture correction with the regular task,
and if that fails does a fallback median estimate.

Parameters
----------
exposure : `lsst.afw.image.Exposure`
    Exposure the normalized calibration flux is measured on.
    This is only used for the bounding box.
catalog : `lsst.afw.table.SourceCatalog`
    SourceCatalog containing measurements to be used to compute
    normalized calibration flux.

Returns
-------
ap_corr_field : `lsst.afw.math.ChebyshevBoundedField`
    Aperture correction field to normalize the calibration flux.
ap_corr_err_field : `lsst.afw.math.ChebyshevBoundedField`
    Aperture correction to adjust the calibration flux error.

◆ run()

lsst.meas.algorithms.normalizedCalibrationFlux.NormalizedCalibrationFluxTask.run	(		self,
		*	,
			exposure,
			catalog )

Measure the Normalized calibration flux.

Parameters
----------
exposure : `lsst.afw.image.Exposure`
    Exposure the normalized calibration flux is measured on.
catalog : `lsst.afw.table.SourceCatalog`
    SourceCatalog containing measurements to be used to compute
    normalized calibration fluxes.  The catalog is modified in-place.

Returns
-------
Struct : `lsst.pipe.base.Struct`
    Contains the following:

    ``ap_corr_map``
        aperture correction map (`lsst.afw.image.ApCorrMap`)
        that contains two entries for the raw flux field:
        - flux field (e.g. config.{raw_calibflux_name}_instFlux): 2d model
        - flux sigma field (e.g. config.{raw_calibflux_name}_instFluxErr): 0 field
