PF1Task

class lsst.faro.measurement.PF1Task(config: PF1Config, *args, **kwargs)

Bases: Task

A Task that computes PF1, the percentage of photometric repeatability measurements that deviate by more than PA2 mmag from the mean.

Notes

The intended usage is to retarget the run method of lsst.faro.measurement.TractMatchedMeasurementTask to PF1Task. This Task uses the same set of photometric residuals that are calculated for the PA1 metric. This metric is calculated on a set of matched visits, and aggregated at the tract level.

Methods Summary

run(metricName, matchedCatalog)

Calculate the percentage of outliers in the photometric repeatability values.

Methods Documentation

run(metricName, matchedCatalog)

Parameters

matchedCataloglsst.afw.table.base.Catalog

Catalog object as created by multiMatch matching of sources from multiple visits.

metricNamestr

The name of the metric.

Returns

measurementlsst.verify.Measurement

Measurement of the percentage of repeatability outliers, and associated metadata.
