Dear Colleagues,

An LDA+U calculation includes in the output a block entitled Occupation for
correlated orbitals, which appears to be the density matrix for the orbitals
being treated with the U and J terms. For example, using L=2 as the correlated
orbitals I get a 5x5 matrix in this block for each atom being treated.

My question is, what basis and in what order is this information being
presented? I am assuming a basis of real spherical harmonics, ordered as M =
-L,-L+1,..+L, is this correct?

Thanks,
Joe Zwanziger
