The FOLP card sets a parameter which determines by what factor the
muffin-tin radii are overlapped for the specified potential index.
We recommend that the AFOLP
card be used (default overlap = 1.15) in cases with severe anisotropy.
FOLP should be used with caution, for example, for hydrogen or for
fitting AXAFS. Typically only values larger than 1 and less than 1.3
should be used, except for hydrogen atoms, where we recommend
the value 0.8. The AFOLP card is ignored when FOLP
is used for a particular potential type.
* +20% overlap of muffin tin with unique potential 1
* -20% overlap of muffin tin with unique potential 2
FOLP 1 1.2 * adjust overlap to fit AXAFS
FOLP 2 0.8 * use 0.8 for hydrogen
