With SIESTA, in a PDOS calculation, is is possible specify the radius around the atoms in which the projection is made? Such option exists in other DFT codes.
Orbitals in SIESTA are localised on atoms thus, SIESTA does not need projections. With SIESTA you get naturally the “chemical” information one is used to.
Plane-wave codes need projections in order to get local information from delocalised basis.
