Gain Notes for Revolution 1016

This is one of the later revolutions in the mission where the calibration
sources have become so weak that for the best energy determination and
IC Gain History table is needed.
 


JEM-X1: 

The Xe line analysis performed using the IC table shows good gain
correction with all except the very first science windows having a Xe level 
within 2-3% of the ideal. As usual however, it is recommended that users
avoid the first few science windows for energy-sensitive applications.


Calibration source number 4 (purple/orange) is no longer
used for calibration purposes since an anode strip directly under the source
has broken and no useable signal comes from this area of the detector any
longer.


JEM-X2: 

The Xe line analysis performed using the IC table shows excellent gain
correction with all except the very first science windows having a Xe level 
within 1-2% of the ideal. As usual however, it is recommended that users
avoid the first few science windows for energy-sensitive applications.
