NPACO and APACO-tag

$$\begin{eqnarray*}\vspace*{1mm} NPACO & =& \mbox{number of slots for pair correla... ...\mbox{maximum distance for the evaluation of PC function in \AA} \end{eqnarray*}$$

Default
NPACO	=	256
APACO	=	16

VASP evaluates the pair-correlation (PC) function each NBLOCK steps and writes the PC-function after NBLOCK*KBLOCK steps to the file PCDAT.
