Comment (by Gabriele Bozzola):

I also tried the new POWER. It took me a while to figure out how to set f0 and M_ADM. I would have expected to find these options among the ones you can specify via command-line, or at least among the “module options”. I saw that there are checks like f0 == FROM_TWOPUNCTURES, so I even considered whether I had to set f0 by setting the variable FROM_TWOPUNCTURES.
