[Pw_forum] The format of potential file in example Al100 workfunction

[Yue-Wen Fang]

Dear users,

In the example of the workfunction for Al(100), we can get a file
"Al100.pot" after executing pp.x after runing pp.x

The header part in the file is shown below *(L1, L2... denote the line
numbers)*:

 L1:      18      18     120      18      18     120       4       1
 L2:    6        5.42350901      0.00000000      6.36396103      0.00000000
     0.00000000      0.00000000
 L3:      74.5076722547        4.0000000000       25.0000000000    11
 L4:  1   Al    3.00
 L5:  1       0.000000000    0.000000000    4.242640687    1
 L6:  2       0.500000000    0.500000000    3.535533906    1
 L7:  3       0.000000000    0.000000000    2.828427125    1
 L8:  4       0.500000000    0.500000000    2.121320344    1

Could anyone explain the meaning of this part? I didn't find the code in
pwscf which generates the header part.

Actually I can guess some of them like FFT grid and coordinates, but I'm
not sure for each number shown above. I appreciate experienced users'
giving a hand. Many thanks.

Bests
Fang
