DcrPrecisionMetric

class rubin_sim.maf.metrics.DcrPrecisionMetric(metric_name='DCRprecision', seeing_col='seeingFwhmGeom', m5_col='fiveSigmaDepth', ha_col='HA', pa_col='paraAngle', filter_col='filter', atm_err=0.01, sed_template='flat', rmag=20.0, **kwargs)

Bases: BaseMetric

Determine how precise a DCR correction could be made

Parameters:

atm_errfloat

Minimum error in photometry centroids introduced by the atmosphere (arcseconds). Default 0.01.

Methods Summary

run(data_slice[, slice_point])

Calculate metric values.

Methods Documentation

run(data_slice, slice_point=None)

Calculate metric values.

Parameters:

data_slicenumpy.recarray

Values passed to metric by the slicer, which the metric will use to calculate metric values at each slice_point.

slice_pointdict or None

Dictionary of slice_point metadata passed to each metric. E.g. the ra/dec of the healpix pixel or opsim fieldId.

Returns:

metricValue: int float or object

The metric value at each slice_point.
