  1. First data Sasha Milov Apr 24, 2006 Sasha Milov HBD upgarde Feb 8, 2005

  2. Data from Craig and Bob These are two samples in the pad exposed to light when the Mesh polarity is Negative (should see light) There is no visible difference between these two samples so I combined them into one Sasha Milov HBD upgarde Feb 8, 2005

  3. Data from Craig and Bob Red points are the combined sample form previous plot. Black points are the signal in the pad which is blocked by the source ( sees no light) Evidently the gain can be somewhat different. So I fitted the slopes at low Np.e. Now let’s assume that different slopes are due to different gains and scale X by that factor. Sasha Milov HBD upgarde Feb 8, 2005

  4. Data from Craig and Bob Red is the same as above, black is rescaled. Evidently we have too different statistics, so one shall normalize them to the same. Sasha Milov HBD upgarde Feb 8, 2005

  5. Data from Craig and Bob Red is the same as above, black is rescaled and normalized to black. Error bars are increased. Conclusion: Not so much to conclude. It’s hard to say if red would leave anything above extrapolated black points with good statistics. There might be more factors involved and the assumptions are somewhat “too strong”. At the moment I thing this is the best we can do with these samples. But the might be something there. Sasha Milov HBD upgarde Feb 8, 2005
