inspiral_range_psd¶

gwpy.astro.inspiral_range_psd(psd: FrequencySeries, snr: float = 8, mass1: float = 1.4, mass2: float = 1.4, horizon: bool = False, **kwargs) → FrequencySeries[source]¶

Calculate the cosmology-corrected inspiral sensitive distance 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 Belczynski et. al (2014):

Parameters:

psdFrequencySeries: The instrumental power-spectral-density data.
snrfloat, optional: The signal-to-noise ratio for which to calculate range.
mass1float, Quantity, optional: The mass of the first binary component (float assumed in solar masses).
mass2float, Quantity, optional: The mass of the second binary component (float assumed in solar masses).
horizonbool, optional: If True, return the maximal ‘horizon’ luminosity distance, otherwise return the angle-averaged comoving distance.
**kwargs: Additional keyword arguments to CBCWaveform.

Returns:

rspecFrequencySeries: The calculated inspiral sensitivity PSD [Mpc^2 / Hz].
