Bases: BaseMetric

Metric to estimate the redshift limit for faint supernovae (x1,color) = (-2.0,0.2)

liststr, optional

Name of the columns used to estimate the metric

coaddbool, optional

to make “coaddition” per night (uses snStacker) Default True

lim_snclass, optional

Reference data used to estimate redshift values (interpolation)

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.
