extract_surf_dens outputs zeros
I'm running utils/seq_extract_radial_surf_dens
on several discs (such as this one) and I only get 0.0000000000000000e+00
as an output. This happens working on the most recent commit (043684ea), on different clusters.
This does not happen for the same exact setup for example using commit edd9f86d, which is the one I was using on my old clusters at MPIA).
