scipy - Separate two signals using python 2.7 -


are there libraries deal separating signals? have scatter graph there appears 2 separate signals, i'd separate these signals , fit curve each separately.

here: 3 scatter graphs try illustrate mean:

enter image description here

the leftmost data, middle data lines drawn in paint tracing 2 signals , rightmost curve of best fit drawn using scipy.optimize.curve_fit. i'd separate 2 signals interfere nonlinear regression, current solution use data below mean on x-axis 1 curve_fit, , data above second curve_fit. wondering if there better way (using python).

i'm using enthought canopy distribution of python.
