compute_moments

pysm3.compute_moments(nu, bnu) → Tuple[float, float]

Compute centroid and bandwidth (stddev) of a bandpass.

Parameters:

nuarray_like

Frequencies in GHz (strictly increasing).

bnuarray_like

Bandpass weights (non-negative). If not normalized, it will be normalized.

Returns:

centroidfloat

First moment (mean frequency), in GHz.

bandwidthfloat

Standard deviation around the centroid, in GHz.
