eobresum_bilby

Thin wrapper around the 'eccentric' branch of https://bitbucket.org/eob_ihes/teobresums/src/master/ which allows compatibility with Bilby https://git.ligo.org/lscsoft/bilby.

The functions defined are:

eccentric_binary_black_hole_eob_resum_nonspinning satisfies the interface for a frequency_domain_source_model used by Bilby's waveform generators. Takes extra keyword arguments of 'TimeDomain' or 'FrequencyDomain', and any keyword arguments used by EOBResum, e.g. ode_abstol, ode_reltol, use_mode_lm

eccentric_binary_black_hole_eob_resum_aligned_spin The same function which allows aligned spins.

native_frequency_domain Uses the frequency domain model provided by EOBResum NOT RECOMMENDED, doesn't seem to produce correct waveforms.

fourier_transform_time_domain Uses time domain model provided by EOBResum and fourier transforms the result before returning to Bilby.

time_domain_eob_resum: Produces time domain EOBResum waveforms.

Example:

kwargs = {'ode_abstol': 1e-10, 
          'ode_reltol': 1e-9, 
          'use_mode_lm': [1] #(2,2) mode
          }

hp, hx = time_domain_eob_resum(dt = 2048., minimum_frequency=15, mass_1=30., mass_2=30, eccentricity=0.1, luminosity_distance=500, theta_jn = 0., phase=0., 
                              chi_1 = 0.1, chi_2 = -0.2, **kwargs)
