FftMetric¶

class rubin_sim.maf.metrics.FftMetric(times_col='expmjd', metric_name='Fft', n_coeffs=100, **kwargs)¶

Calculate a truncated FFT of the exposure times.

Methods Summary

`reduce_peak`(fft_coeff)
`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.
