relativebilbying
This code is a complement to the bilby
package and enables one to perform relative binning in bilby
. We note that, for the moment, the code only implements relative binning without higher order modes.
Relative binning is a method to perform bayesian parameter inference for gravitational waves in a faster way. It has been developped in Zackay et al, Dai et al. Additionally, attempts have been made to develop relative binning for higher-order modes waveforms (see Leslie et al).
In this repo, we use the ideas from Zackay et al and convert them into a bilby compatible format, making it easier to use.
