The EXAFS card is used to change the maximum value of for EXAFS
calculations. is set by xkmax, and the default value is

the user may be prompted to increase dimensions in the file `dim.h'
and recompile the code. For high calculations it might be necessary
to make smaller steps using the RGRID card.
