Gain Notes for Revolution 2010

N.B: This revolution was calibrated using CONS data since the NRT data was compromised
by network problems at ISDC. Consequently, the corrected gain history table was not
available for the CONS processing 001, and archived corrected data for this processing
and this revolution will be rubbish. Always start your JEM-X data analysis from COR level
using a downloaded corrected gain history table.


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.

To get optimal results with this revolution it is necessary to use the IC gain history.
See notes in revolutions prior to revolution 1433 to find out how to do this
if you don't already know.

All offline gain/energy corrections (including the IC tables) are based on the
two Fe calibration sources in JEM-X1, for both units.

Latest OSA software (version 10 and higher) automatically cuts out the first
Science windows of data from each revolution to ensure that people do not use data
from the instrument-settling period. This process can be overruled, but only by
experienced users.
	
JEM-X1 rating: Excellent (Xe line positions within 2% of ideal)

JEM-X2 rating: Excellent

The JEM-X2 corrections are based on the JEM-X1 Fe calibration sources, since
all the Cd sources are now to weak to use.
