gw_frequencies

A convenience package to make reduced frequency arrays for the representation of gravitational waveforms.

It makes available the following functions; here they are documented very shortly, see their docstrings (help(func_name) in an interactive console) for more details.

• seglen_from_freq, which computes the duration T(f), in seconds, of a gravitational wave signal starting at a given frequency, in Hertz.
• high_frequency_grid, a uniform grid in frequency
• low_frequency_grid, a non-uniform grid in frequency satisfying dN/df = 1/T(f) at each frequency
• mixed_frequency_grid, a grid with the low-frequency specification below some pivot and the high-frequency specification above it.

The main idea here is the low_frequency_grid, which is a slightly different implementation of the concepts outlined by Vinciguerra et al, 2017.

To install this package, do:

pip install gw-frequencies

To import the required functions, do

from gw_frequencies.multibanding import <func_name>

where <func name> is the name of the function you want.
