Subject: grey filter

Folks,

Checking JEM-X2 up to orbit 149, we spent a total of 275 days in 
full imaging mode (including Crab calibration). A few statistics:

Average grey filter: 2.5%
Obs time in full imaging, where the sci-win is affected by GF: 12.9%
Number of full imaging sci-win, where the GF is active: 8.6% 
Mean transmission in sci-win, where GF is active: 80%
