Error(s) when using aligned spin waveforms
I am doing some runs using the aligned spin waveform SEOBNRv4_ROM
I originally ran with something like this .prior (with help from Isobel)
mass_1 = Uniform(name='mass_1', minimum=10, maximum=100, unit='$M_{\\odot}$')
mass_2 = Uniform(name='mass_2', minimum=10, maximum=100, unit='$M_{\\odot}$')
a_1 = bilby.gw.prior.AlignedSpin(a_prior=Uniform(0, 0.99), z_prior=Uniform(-1, 1), name='chi_1', latex_label='$\\chi_1$')
a_2 = bilby.gw.prior.AlignedSpin(a_prior=Uniform(0, 0.99), z_prior=Uniform(-1, 1), name='chi_2', latex_label='$\\chi_2$')
tilt_1 = 0 #Sine(name='tilt_1')
tilt_2 = 0 #Sine(name='tilt_2')
phi_12 = Uniform(name='phi_12', minimum=0, maximum=2 * np.pi)
phi_jl = Uniform(name='phi_jl', minimum=0, maximum=2 * np.pi)
# Here we use a luminosity distance consistent with LAL analyses for comparison.
luminosity_distance = bilby.core.prior.PowerLaw(alpha=2, name='luminosity_distance', minimum=1000, maximum=7000, unit='Mpc', latex_label='$d_L$')
dec = Cosine(name='dec')
ra = Uniform(name='ra', minimum=0, maximum=2 * np.pi)
iota = Sine(name='iota')
psi = Uniform(name='psi', minimum=0, maximum=np.pi)
phase = Uniform(name='phase', minimum=0, maximum=2 * np.pi)which fails after the nested sampling (generating posterior samples) with:
