It is the latest developers release, and I use the ct-hyb. It uses the lates Alea, as far as I understanf (at least that is where I tried to put together my meager knowledge on the different parts of the output). Presently I use Python and access the features of timeseries via ar['/simulation/results/density_%i/timeseries/data/@binsize'%orb] Is there a comprehensive manual on how to access the functions mentioned below somewhere on the ALPS-Wiki? I have been scanning all possible places without getting anywhere ... I'll try to make the measurments such that I am beyond the autocorrelation time. Thus I assume I can take the "Yes, you can" from the answer. Best Thomas
