 - no timewarps
 - deadtime aida05 c. 37% and 39% due to high SC41 scaler input to MACB - issue subsequently fixed 
 - deadtime aida04 c. 4%, all other FEE64s <<1%

Data analysis assumes

- all LEC ADC data channels with valid ADC offset included (507 of 512 channels)
      LEC calibration ADC offset only

- no clustering

- no multiplex timestamp correction

- no p+n junction side - n+n Ohmic side correlation time gates

- FEE64 *not* DSSSD strip ordering

- hardware - slow comparator setting p+n junction FEE64s 100keV, n+n Ohmic FEE64s 150keV

- LEC energy difference +/- 168keV

- HEC energy difference +/- 1.68GeV

- valid LEC events

p+n junction side multiplicity = 1 and n+n Ohmic side multiplicity = 1
   151keV < LEC energy < 1000keV
    to select candidate beta events
    standalone analysis of AIDA data, no downstream veto detector

- valid HEC events
   p+n junction side multiplicity > 0 and n+n Ohmic side multiplicity > 0
   (x,y) strips corresponding to maximum energy
   p+n junction and n+n Ohmic side HEC

- HEC veto 
   not available - only 1x AIDA DSSSD installed

- per pixel implant-decay correlations

- end of event 
   difference in WR timestamp between successive ADC data items > 2500 and overall event length < 33us

per FEE64 LEC ADC data items 268ms/channel - attachments 3-5
- all
- 150keV < energy < 1500keV
- energy > 1500keV

absence of high instantaneous rates on spill cf. S181, S100, S505 etc
spill structure visible for energies > 1500keV - probably to be expected as majority of such events should be light ions

per FEE64 HEC ADC data items 268ms/channel - attachments 6-8

- all
- 100MeV < energy < 1000MeV
- energy > 1000MeV

- blue - forward
- cyan - backward

Note
- no FRS PID
- no HEC dE
- no HEC veto
- no HEC energy gates - assume all events within x-y window *stop* in AIDA DSSSD - 82Nb events known to overlap in x-y with (longer-lived, more numerous) 83Nb events
- no front-back time difference
- no clustering
- *all* LEC channels with valid ADC offsets (507 of 512) included *except* 2x strips 130 & 136
