While Py2exe works flawlessly the resulting dist/ folder with the executable contains a large number (10-15) of support files (.dll, .pyd, .zip).

Trying to plot a spectrum, ie, velocity versus intensity, with lower x axis = velocity, on the upper twin axis = frequency The relationship between them (doppler formula) is f = (1-v/c)*f_0 where f is the resulting frequency, v the velocity, c the speed of light, and f_0 the frequency at v=0, ie. the v_lsr. I have tried to solve ...
