inspiral_range_psd¶

gwpy.astro.inspiral_range_psd(psd, snr=8, mass1=1.4, mass2=1.4, horizon=False)[source]¶

Approximate the inspiral sensitive distance PSD from a GW strain PSD

This method returns the power spectral density (in Mpc**2 / Hz) to which a compact binary inspiral with the given component masses would be detectable given the instrumental PSD. The calculation is defined in:

https://dcc.ligo.org/LIGO-T030276/public

Parameters

psd : FrequencySeries

the instrumental power-spectral-density data

snr : float, optional

the signal-to-noise ratio for which to calculate range, default: 8

mass1 : float, Quantity, optional

the mass (float assumed in solar masses) of the first binary component, default: 1.4

mass2 : float, Quantity, optional

the mass (float assumed in solar masses) of the second binary component, default: 1.4

horizon : bool, optional

if True, return the maximal ‘horizon’ sensitive distance, otherwise return the angle-averaged range, default: False

Returns

rspec : FrequencySeries

the calculated inspiral sensitivity PSD [Mpc^2 / Hz]
