Models with limb-darkening coefficient

[IvaPIvanova]

I'm using MulensModel with a set of simulated data to generate light curves for single-lens microlensing events. I've created both PSPL models and finite source models, and am now looking to update them by introducing limb-darkening. I have a linear limb-darkening coefficient for each star, which is an output from the simulation itself (the code handles computation of linear limb-darkening coefficients using precomputed spline interpolates fitted to data). We cover a range of values for rho so I've successfully used the code below thus far:

if rho < 0.001:
model_finitesource.set_magnification_methods([t_1,'point_source',t_2])
elif rho <0.1:
model_finitesource.set_magnification_methods([t_1,'finite_source_uniform_Gould94',t_2])
else:
model_finitesource.set_magnification_methods([t_1,'finite_source_uniform_Lee09',t_2])

However, I'm struggling to switch to using finite_source_LD_Yoo04 (instead of finite_source_uniform_Gould94) and finite_source_LD_Lee09 (instead of finite_source_uniform_Lee09) with a pre-defined limb-darkening coefficient as a variable in the script. I'm not sure on the correct syntax of .set_magnification_methods() in my case. I tried following example_25_LD.py to adapt with my code but was unsuccessful (I get the TypeError: init() got an unexpected keyword argument 'magnification_methods' at line uniform_model = mm.Model( )

I would highly appreciate some help with implementing pre-computed LDC with the finite_source_LD_Yoo04 and finite_source_uniform_Lee09 models.

Hi,

However, I'm struggling to switch to using finite_source_LD_Yoo04 (instead of finite_source_uniform_Gould94)

It's not clear what the problem is. Your Model.set_magnification_methods() code seems fine. You just need to change the method name and provide limb darkening coefficient using Model.set_limb_coeff_gamma() or Model.set_limb_coeff_u() depending on the convention you use. If these explanations are not enough, then please copy-paste example code that fails.
You later link example 25, which was considered at some point, but is not among examples now (see examples/ dir).

Hi, thank you so much for your quick response. I had just gotten myself with that example 25 confused on how to set the LDC. All good now. Thanks for your help!
