Specific IMRPhenomXPHM-ST implementation
As far as I am aware, IMRPhenomXPHM
with the SpinTaylor angles is called by setting approximant=IMRPhenomXPHM
and passing appropriate flags in the LALDict
. To reduce the possibility of incorrectly calling this waveform in e.g. PE, I think it would be simpler to add a new approximant in lalsimulation
(possibly IMRPhenomXPHM-ST
) which sets these flags for you.
