ChangeLog for emos-aduconv
==========================
VERSION 0.5 - 2000-06-23 (DL)
-----------
        The initial flight calibration revealed discrepancies at the O edge
        and the lowest energy reponses. These were attributed mainly to 
        systematic  errors in the monitoring process at the Orsay synchrotron.
        New empirical fits to the data were provided by Leicester, and these 
        have been compared with new SCISIM runs, utilising the best latest 
        electrode structure used in the Leicester analystical QE model fit. A 
        combination of LUX data, and an extension BELOW the Si L edge for the 
        SCISIM data allows a hopefully better fit. In addition I have modified
        the QE's for the outer CCDs of each camera, where there are systematic
        differences in QE at > 5keV. These can be attributed to ddifferences
        in silicon resistivity translating to different depletion depths. The 
        QE data for this at Orsay is equivocal, so I take average trends in
        increased efficiency between 5 and 12keV and allocate a best estimate 
        of increased depletion depth to this, and in return modify the overall
        QE curves as a result. I am suspicious, though that all QE's are 
        GREATER tahn the central CCD, and this may indicate a systematic bias
        in the measurment method at Orsay.

        The new data sets should give good results to about 10% accuracy at 
        worst case small energy scales (eg EXAFS scales at silicon edges etc.)
