StarCountMassMetric

class rubin_sim.maf.maf_contrib.StarCountMassMetric(**kwargs)

Bases: BaseMetric

Find the number of stars in a given field in the mass range fainter than magnitude 16 and bright enough to have noise less than 0.03 in a given band. M1 and m2 are the upper and lower limits of the mass range. ‘band’ is the band to be observed.

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.
