hi, i was wandering how in this ( https://arxiv.org/abs/2307.13482
2307.13482_2.pdf
) paper they did fitting?! there is no parameters used for primary. but they use semidetached constraint. if i want to try fitting like the system they use what must i do?? for requiv1? and for teff1?? i got errors in every try i did. requiv_max error and ld_coeff errors and atm error that they use ck2004 but i cant, and soooo many errors. so in the end im tired and confused, help me. :((((((((

See the tutorial on semi-detached systems here

In that code you don't ever load a binary nor the datafile, so this is not a minimal working example.

Above I explained that you probably need to set the limb-darkening but you only set the bolometric limb-darkening (used for irradiation).
The secondary atmosphere probably also goes out of bounds if you aren't setting it to blackbody anywhere.
You are trying to sample/set the secondary requiv but this is automatically set by the semi-detached constraint, so cannot be done.

It looks like its actually the run_compute with sample_num=60 that is stalling. I'm guessing that is because the initial samples are all getting rejected and are unable to compute. My suggestion would be to check your sampling distribution carefully to make sure it is valid.

so if i dont set secondary to be constraint i got overflowing error! this in my main problem, how they did it in paper that i mentioned?

[kecnry]

To see the actual errors that are causing the samples to be immediately rejected, you can always manually sample your distribution and adopt the face-values (with sample_distribution_collection('NNN', set_value=True) and call run_compute() on those.

You can also reach out to the authors of the paper if you're unable to reproduce their results. Sometimes some details are not included in the text that can be important to reproduce.

OK, thanks a lot kyle.
