Dan Foreman-Mackey (NYU) made a few surface changes to the interface in order to write a Python wrapper (with the permission of the original author).
pip install acor
sudo if you really need it.
git clone https://github.com/dfm/acor.git
cd acor python setup.py install
to compile and install the module
acor in your Python path. The only
dependency is NumPy (including the
python-numpy-dev packages which you might have to
install separately on some systems).
Given some time series
x, you can estimate the autocorrelation time
import acor tau, mean, sigma = acor.acor(x)
