This function aligns the three phase parts (inspiral, intermediate and merger-rindown) such that they are c^1 continuous at the transition frequencies Defined in VIII.

Full IMR Waveforms arXiv:1508.07253 Rholm was added when IMRPhenomHM (high mode) was added. Rholm = fRD22/fRDlm. For PhenomD (only (l,m)=(2,2)) this is just equal to 1. and PhenomD is recovered. Taulm = fDMlm/fDM22. Ratio of ringdown damping times. Again, when Taulm = 1.0 then PhenomD is recovered.

Subtract 3PN spin-spin term below as this is in LAL's TaylorF2 implementation (LALSimInspiralPNCoefficients.c -> XLALSimInspiralPNPhasing_F2), but was not available when PhenomD was tuned.
