Gain Notes for Revolution 401
	
JEM-X2: This is the second full revolution for JEM-X2 since its activation and
warm-up revolution 399. JEM-X2 was activated specifically for the Earth
Observations. The data now presented here (gain history, smoothing and
Xe line) were obtained using the ISDC-generated gain history table produced 
with the CONS (consolidated) pipeline. This is the data that is archived in
/isdc/arc/rev_2. It is the data that is delivered to observers. This data has
a good gain history table which is smoothed well. All the science data from this
revolution should be useable.
Some large glitches are visible on source 1 (black/red), but these in no way
affect the science data.

100 second observations: The Earth Observations for this revolution were also
released cut up into 100 second science windows, to allow time resolved 
imaging of the occultaion. This data was processed with the correct software
(see warning below), and produced fine data, gain history and gain correction.
These results are also shown on the table.

WARNING: The data that was originally produced by the NRT pipeline was not
useable. The gain history table was generated with antiquated software and
was consequently filled almost entirely with null data. Use only the data from
the archive.

The new Xe peak analysis was added after determination of new improved calibration
reference channels for JEM-X2 IMOD epochs 12 and 13 (revs 311 to 510 and 511
onward, respectively). This brings the Xe level closer to the 29.6 keV ideal
value. However, there is so little data to analyse that no great importance can
be attached to this analysis or to the average position of the Xe line since
a whole revolution Xe evolution is not possible.
