Reduced Light Curve: Signal-minus-Background, normalized on Io, bins of 4 frames



The target at the begining, mid time and end of the event:



In this measurement I used the double PSF fitting in Tangra where the 'star group', including both Ganymede and Europa, has been fitted and measured simultaneously.



Observation:

Using WAT910-BD; Gamma = off; Gain = 25; 1/500 sec exposure; AAV stacking of 16 frames in one; F/3.3 reducer



Prediction:
