Because I have been working on this task for all too long a time, I provisionally pushed my current codes as tickets/ |

Test passed. The problem turned out to be the too narrow sampling interval of the cross correlation function, for neighboring samples made from too similar linear-combinations of random variables, or observed spectrum, cause their covariance matrix almost defective, troubling scipy.optimize.curve_fit(), resulting in strange output. I'm making PR. |
