PCDAT

The PCDAT file contains the pair correlation function. For dynamic simulations (IBRION$\geq$0) an averaged pair correlation is written to the file (see also NBLOCK, KBLOCK, NPACO and APACO).

A sample output of the PCDAT file for a 64 atom cell of Si looks as follows:

   1  64   1   0  0.2002283E+02  0.2000000E+04

Here is the description of each line:

• Line 1: 1 (always 1), number of ions, 1, 0 , , temperature
