NormalizedCalibrationFluxTask¶

NormalizedCalibrationFluxTask takes an unnormalized calibration flux (e.g. base_CompensatedTophatFlux_12) and normalizes it to an overall calibration flux (e.g. base_CircularApertureFlux_12_0). This task is essentially a specialized wrapper around lsst.meas.algorithms.MeasureApCorrTask that can measure and/or apply an aperture correction map into a new field name given by the normalized_calibflux_name config field.

Python API summary¶

Retargetable subtasks¶

fallback_source_selector¶

Default

'science'

Field type

Single-selection RegistryField

Choices

'science': lsst.meas.algorithms.sourceSelector.ScienceSourceSelectorTask
'references': lsst.meas.algorithms.sourceSelector.ReferenceSourceSelectorTask
'null': lsst.meas.algorithms.sourceSelector.NullSourceSelectorTask
'objectSize': lsst.meas.algorithms.objectSizeStarSelector.ObjectSizeStarSelectorTask

'astrometry': lsst.meas.algorithms.astrometrySourceSelector.AstrometrySourceSelectorTask
'matcher': lsst.meas.algorithms.matcherSourceSelector.MatcherSourceSelectorTask

Selector that is used as a fallback if the full aperture correction fails.

measure_ap_corr¶

Default: lsst.meas.algorithms.measureApCorr.MeasureApCorrTask
Field type: ConfigurableField

Subtask to measure aperture corrections.

Configuration fields¶

do_measure_ap_corr¶

Default: True
Field type: bool Field

Measure the aperture correction? (Otherwise, just apply.)

do_set_calib_slot¶

Default: True
Field type: bool Field

Set the calib flux slot to the normalized flux?

normalized_calibflux_name¶

Default: 'base_NormalizedCompensatedTophatFlux'
Field type: str Field

Name of normalized calibration flux.

raw_calibflux_name¶

Default: 'base_CompensatedTophatFlux_12'
Field type: str Field

Name of raw calibration flux to normalize.
