Bases: BaseMetric

figure of merit to measure the coverage the time gaps in same and different filter pairs; FoM is defined as sum of Nv / standard deviation after a clip; Parameters:

colname: list, [‘observationStartMJD’, ‘filter’, ‘fiveSigmaDepth’] fltpairs: filter pair, default [‘uu’, ‘ug’, ‘ur’, ‘ui’, ‘uz’,’uy’,

‘gg’, ‘gr’, ‘gi’, ‘gz’, ‘gy’, ‘rr’, ‘ri’, ‘rz’, ‘ry’, ‘ii’, ‘iz’, ‘iy’, ‘zz’, ‘zy’, ‘yy’]

mag_lim: list, fiveSigmaDepth threshold each filter, default {‘u’:18, ‘g’:18, ‘r’:18, ‘i’:18, ‘z’:18, ‘y’:18} bins_same: np.array, bins to get histogram for same-filter pair ; bins_diff: np.array, bins to get histogram for diff-filter pair ; nv_clip: number of visits of pairs to clip, std is calculated below nv_clip allgaps: boolean, all possible pairs if True, else consider only nearest

Returns:

result: sum of fom for all filterpairs,

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.
