class rubin_sim.maf.metrics.CountExplimMetric(col=None, min_exp=20.0, expected_exp=30.0, exp_col='visitExposureTime', **kwargs)

Bases: BaseMetric

Count the number of x second visits. Useful for rejecting very short exposures and counting 60s exposures as 2 visits.

Methods Summary

run(data_slice[, slice_point])

Calculate metric values.

Methods Documentation

run(data_slice, slice_point=None)

Calculate metric values.


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.

metricValue: int float or object

The metric value at each slice_point.
