Dear Roozbeh,

That's the number of shells in the atom. There are some programs, which
read that number. However, most SK-files do not have that field.
> 5*0.0 -1.367223784172e+00 -2.360598690066e+00 0.0 -2.995723510316e-01

Not, that's just the old Fortran-convention, which turn 5*0.0 at reading
into 5 times the item 0.0. So it is 20 columns, as the manual says. Have
a look at newer generation of SK-files (e.g. 3ob, ob2, etc.), they do
not use that convention any more.
Best regards,
Bálint
