Luciano, I think GRHydro inherited the atmosphere_mask from Whisky. In Whisky the atmosphere_mask was introduced to allow to set the RHS to zero for points within the atmosphere and to avoid to run Con2Prim in those points. I do not think there is any advantage in using it and there should be no problem in setting the points to atmosphere locally without a mask (in Spritz, which comes from WhiskyMHD, we removed indeed the usage of masks).
