Astrophysics Utilities (`gwpy.astro`)#

Methods for sensitivity calculations of gravitational-wave interferometer data.

The LIGO project measures time-dependent sensitivity by calculating the distance at which the gravitational-wave signature of a binary neutron star (BNS) inspiral would be recorded by an instrument with a signal-to-noise ratio (SNR) of 8. In most of the literature, this is known as the ‘inspiral range’ or the ‘horizon distance’.
