wild guess, but i'd say it looks like you are writing
a 3D array in binary, and i'll guess it is a floating point number array.

so in IDL do

datain = fltarr(np1, np2, np3)

openr,1,'filename'
readu,1,datain
close,1

This won't work, cause you'll have to figure out
byteswapping, and dimension order.
So, make a fake file in fortran so you know what the
data is (numbers like delta[1,1,1] = 111, delta[ 4,8,5] = 485 etc.)
and see what you get. Then simply debug it into existence.

Cheers,
bob
