parameters for ellc_emcee

[TeHanHunter]

Hi! I'm using ellc_emcee for fitting binary systems. For systems that I don't know parameters, what should I enter for that entry? For example, if I don't know "r_1 = R_1/a =", what should I enter to make it free?

Sometimes, I got error message like this:

Initialising walkers ... /home/tehan/.local/bin/ellc_emcee:36: FutureWarning: rcond parameter will change to the default of machine precision times max(M, N) where M and N are the input matrix dimensions. To use the future default and silence this warning we advise to pass rcond=None, to keep using the old, explicitly pass rcond=-1. c_s,resid,rank,sval = np.linalg.lstsq(A_s,b) End ELLC - error calling starshape End ELLC - error calling starshape End ELLC - error calling starshape End ELLC - error calling starshape End ELLC - error calling starshape End ELLC - error calling starshape End ELLC - error calling starshape End ELLC - error calling starshape End ELLC - error calling starshape End ELLC - error calling starshape End ELLC - error calling starshape End ELLC - error calling starshape End ELLC - error calling starshape End ELLC - error calling starshape Initialised 200 walkers after 214 trials

I think this is the result of me entering wrong parameters. Thank you so much for helping!
