Hi Lydia,
Just to make sure, by 'ldos00.dat' file you actually mean 'rholNN.dat' files? The FEFF8 manual does not mention any 'ldos00.dat' file, and 'rholNN.dat' files are the output files of the LDOS card.
In FEFF8.0 the LDOS was in files called rholNN.dat. In FEFF8.2 this was changed to ldosNN.dat, with a cleaned up output format. Sorry for the possible confusion. J. Rehr
