Attachment 2 - analysis from *end* of file AIDA75_1

2D spectrum - FEE # versus timestamp (100us/channel)

1D spectrum - projection of timestamp data for FEE # = 6

Conclude data synchronised at beginning and end of AIDA75_1. 
Period of pulser data ~36ch = 3.6ms => pulser frequency ~ 280Hz

Attachment 3 - analysis around ts=0x18bacd75c4 +/- 20000000 (dec)

Conclude FEE # 6 stops producing ADC data c. ch 353

Attachment 4 - analysis around ts=0x18cac6144b +/- 20000000 (dec)

Conclude FEE # 6 starts producing ADC data c. ch 28

Spectrum s4100 y-channel calculated as follows
