Tweak to description.

Note also the divergence of the spectra for the two processing systems - azspec appears to be better. Perhaps the bump is due in part to smear correction and in part due to poor calibration at the edge of the ccd?

  • Ticket #113 – Description

    v1 v2  
    1 Eagle and Hawk spectra over water both seem to have an unexplained "bump" at around 970nm (upper end of Eagle's range, lower end of Hawk's). Water IR reflectance shouldn't have this bump, should just be black.
     1Eagle and Hawk spectra over water both seem to have an unexplained "bump" at around 970nm (upper end of Eagle's range, lower end of Hawk's). Water IR reflectance shouldn't have this bump, should just be black (exponential decay curve to very low values).

    33For graph below, red and pink lines are Eagle and Hawk respectively from a Caligeo-processed level 1 file, green and blue lines are Eagle and Hawk respectively from an azspec-processed level 1 file (spikes in azspec SWIR are being dealt with in ticket #110). It can be seen that Eagle starts to rise slightly at ~960nm and Hawk is far too high until about 1140nm (if not higher - hard to tell)
