The EXAFS card is used to change the maximum value of $k$ for EXAFS calculations. $k$ is set by xkmax, and the default value is 20 Å$^{-1}$. The code can calculate to even higher values, however, the user may be prompted to increase dimensions in the file `dim.h' and recompile the code. For high $k$ calculations it might be necessary to make smaller steps using the RGRID card.
