NormalizedCalibrationFluxTask

class lsst.meas.algorithms.NormalizedCalibrationFluxTask(schema, **kwargs)

Bases: Task

Task to measure the normalized calibration flux.

Parameters

schemalsst.afw.table.Schema

Schema for the input table; will be modified in place.

**kwargsdict

Additional kwargs to pass to lsst.pipe.base.Task.__init__()

Raises

NormalizedCalibrationFluxError

Raised if there are not enough sources to calculate normalization.

Methods Summary

run(*, exposure, catalog)

Measure the Normalized calibration flux.

Methods Documentation

run(*, exposure, catalog)

Measure the Normalized calibration flux.

Parameters

exposurelsst.afw.image.Exposure

Exposure the normalized calibration flux is measured on.

cataloglsst.afw.table.SourceCatalog

SourceCatalog containing measurements to be used to compute normalized calibration fluxes. The catalog is modified in-place.

Returns

Structlsst.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
