Adding the tilts at infinity calculation to LALSimulation

Nathan Johnson-McDaniel requested to merge waveforms/reviews/lalsuite:spin-tilts-infinity into master

Description

This implements the tilts at infinity calculation including regularized precession-averaged equations and hybrid orbit-averaged and precession-averaged evolution as described in this draft.

It introduces a new tilts_at_infinity Python module in LALSimulation containing this code.

API Changes and Justification

Backwards Compatible Changes

  • This change removes an existing API

Review Status

This code was reviewed here by @sylvain.marsat, @marta.colleoni, @lucy.thomas, and @eleanor.hamilton

@duncanmmacleod approved only running the regression test for the hybrid evolution in lalsimulation:conda, since it runs quickly there but takes much longer in other parts of the CI and even causes the coverage job to time out.
