We observed auto changes of the number of X-ray pulses last night and tonight.

It is related to 500 um thick Si attenuator in XTD2_ATT.

Even with 2.4 mm thick CVD (XTD2_ATT) IN, the number of pulses @SA1 changes to 28 whenever we insert 500 um thick Si attenuator.

Watchdog triggered this process. It has to be updated.

First row in the atttachment: The number of X-ray pulses @ SA1

Second row in the attachment: Status of 2.4 mm thick CVD in XTD2_ATT

Third row in the attachment: Status of 0.5 mm thick Si in XTD2_ATT
