As I checked the latest version of the manual, I came across with this (in page 112):
It is not present in 2013 manual and I guess it is something implemented in current beta. In the preceding pages, if I am not missing, relevant information about other expectation values are given but not about the molecular density. Does this mean that plotting finite system charge densities without spherical symmetry is implemented in CASINO? It seems to be still in the todo list at Vallico webpage. If it is finite system implementation, I would be happy to learn about its format and how grid density can be changed.START MOLECULAR DENSITY
