This is for Mathematica 9.

(* !!  Export[] "Data", Import "RawData" !!   *)

If one tries to Export[] "RawData" it complains. So one needs to:

  Export["file.fits",{"Data"->data},"Rules"]


But Import[]ing "Data" yields an array scaled from 0-1. So to get back the arbitrary floating point array that one Export[]ed, one needs to:

  Import["file.fits", "RawData"]

Weird asymmetry!
