class rubin_sim.maf.metrics.MinTimeBetweenStatesMetric(change_col='filter', time_col='observationStartMJD', metric_name=None, **kwargs)

Bases: BaseMetric

Compute the minimum time between changes of state in a column value. (useful for calculating fastest time between filter changes in particular). Returns delta time in minutes!

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.
