C code for SEOBNRv2 reduced order model (equal spin version). See CQG 31 195010, 2014, arXiv:1402.4146 for details.

- Michael Puerrer, John Veitch
This is a frequency domain model that approximates the time domain SEOBNRv2 model with equal spins.
The binary data files are available at https://dcc.ligo.org/T1400701-v1. Put the untared data into a location in your LAL_DATA_PATH.
- Note
- Note that due to its construction the iFFT of the ROM has a small (~ 20 M) offset in the peak time that scales with total mass as compared to the time-domain SEOBNRv2 model.
-
Parameter ranges:
- 0.01 <= eta <= 0.25
- -1 <= chi <= 0.99
- Mtot >= 1.4Msun
Equal spin chi = chi1 = chi2 in terms of aligned component spins chi1, chi2. Symmetric mass-ratio eta = m1*m2/(m1+m2)^2. Total mass Mtot.
