SEOBNRv1 Reduced Order Model (Effective Spin)
C code for SEOBNRv1 reduced order model (equal spin version). See CQG 31 195010, 2014, arXiv:1402.4146 for details. Author Michael Puerrer, John Veitch This is a frequency domain model that approximates the time domain SEOBNRv1 model with equal spins. Note that SEOBNRv2 supersedes SEOBNRv1. 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 SEOBNRv1 model. Due to non-smoothness in SEOBNRv1 at chi1=chi2 ~ -0.8 and 20 <= q <= 40 the ROM deviates from the SEOBNRv1 behavior there. See arXiv:1402.4146, Fig 7, Fig 11, and Fig 13 for details. Parameter ranges: 1 <= q <= 100 -1 <= chi <= 0.6 Mtot >= 1.4Msun Equal spin chi = chi1 = chi2. Asymmetric mass-ratio q = max(m1/m2, m2/m1). Total mass Mtot.
