Definitions of Variables

record 1

header 		 a80 		 file header

record 2

delpot 		 real 		 mesh resolution in Å

cutpot 		 real 		 cutoff used to define tables Å

ngrid 		 integer 		 number of grid points in tables

The subsequent records define each tabulated potential in turn, in the order indicated by the specification in the FIELD file. Each potential is defined by a header record and a set of data records with the potential and force tables.

header record:

atom 1		 a8 		 first atom type 

atom 2		 a8 		 second atom type 

potential data records: (number of data records $=$ $Int$((ngrid+3)/4))

data 1 		 real 		 data item 1

data 2 		 real 		 data item 2

data 3 		 real 		 data item 3

data 4 		 real 		 data item 4

force data records: (number of data records $=$ $Int$((ngrid+3)/4))

data 1 		 real 		 data item 1

data 2 		 real 		 data item 2

data 3 		 real 		 data item 3

data 4 		 real 		 data item 4
