NASA Ames Data Format: FFI 4010

Symbols used

X^s		s^th independent variable (s from 1 to 4). Its values are real. X¹, X² and X³ are the bounded independent variables, X⁴ is the unbounded independent variable. Only X⁴ is recorded in the data section of the file. X¹, X² and X³ are recorded in the file header (see Metadata Format 4010).
NX^s		Number of values of X^s for s < 4
NV		Number of primary dependent variables
NAUXV		Number of auxiliary dependent variables
V_n		n^th primary variable
A_a		a^th auxiliary variable (depends on X⁴ only — independent of X¹, X² and X³). Its values are real.

[ X⁴(m) ( A_a(m), a=1,NAUXV ) ]
[ V_n(i,j,k,m), i=1,NX¹ ] j=1,NX² k=1,NX³ n=1,NV
