     Calibration is discussed in the instrument template and a sensitivity
     table is provided there. The EUV was calibrated at both the Arizona
     facility and at the LASP facility. In-flight cross-calibration with the
     UVS instrument, particularly at Lyman-alpha, yielded a third sensitivity.
     The Tucson and LASP sensitivity measurements did not agree. A paper
     comparing Galileo EUV calibration with the Voyager UVS calibration was
     prepared which stated that the galileo EUV calibration was within 15%.
     Also, the EUV sensitivity appears to have changed during the mission,
     based on the Earth1 and Earth2 star/cross-calibration activities and
     subsequent cross-calibration. Details are not currently specified.
     The data were analyzed using a 128-pixel interpolated array based on the
     the Tuscon calibarion from Sandel. This interpolated array is in the
     calibration directory, named EUV_128POINT_CAL.DAT .
