    The IFG table contains the raw interferogram data.  The
    interferogram data is only downlinked when requested and
    can only be requested for a single detector per observation.

    The IFG array contains 1600 points for a short scan
    (OBS Table, SCAN_LENGTH = 1), and 3200 points for a long scan
    (OBS Table, SCAN_LENGTH = 2)."
