      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

- HEC energy difference +/- 1.68GeV

- valid LEC events

p+n junction side multiplicity = 1 and n+n Ohmic side multiplicity = 1

LEC energy > 151keV
    to select candidate beta  and alpha events - will include light ions

(x,y) strips corresponding to maximum energy
  p+n junction and n+n Ohmic side HEC

- HEC veto 
   p+n junction side multiplicity > 0 or n+n Ohmic side multiplicity > 0

Attachments 3-6 - per FEE64 LEC data item rates 268ms/channel - common x and y scales
 - no conditions
 - 150keV < energy < 1500keV
 - energy > 1500keV

Some deadtime observed on spill, none observed off spill. No significant variation in per FEE64 LEC data rates.

Attachments 7-8 - per FEE64 LEC hit patterns
 - 150keV < energy < 1500keV
 - energy > 1500keV

Aside from usual hot channels at cable/DSSSD boundaries good hit pattern observed. For > 1500keV events observe flat field in x-plane, focussed in y-plane.

Attachments 9-11 - per FEE64 HEC data item rates 268ms/channel - common x and y scales
 - no conditions
 - 100MeV < energy < 1000MeV
 - energy > 1000MeV

Note hot HEC channel in aida08 - should be disabled.

Attachment 12 - per DSSSD decay and implant rates 262us/channel - common x and y scales

Attachment 13 - per DSSSD LEC m_p versus m_n 
 - no conditions

Attachment 14 - per DSSSD LEC p strip versus n strip
 - no conditions

Attachments 15-16 - per DSSSD LEC E_p versus E_n - x and y-axes 20keV/channel
 - LEC energy difference +/- 2000 channels (+/- 11200keV)

Attachments 17-18 - per DSSSD p strip versus n strip
 - HEC-LEC time difference <1s
 - HEC-LEC time difference <100s

Attachment 19 -  per DSSSD HEC m_p versus m_n

Attachment 20 - per DSSSD HEC p strip versus n strip
 - no conditions
 - z_hec=1 => implant stops in DSSSD#1
 - z_hec=3 => implant hits DSSSD#1 and DSSSD#2 but does not necessarily stop in DSSSD#2

Attachment 21 - per DSSSD HEC E_p versus E_n - x and y axes 20MeV/channel

Attachment 22 - DSSSD#1 HEC E_p versus DSSSD#2 HEC E_p - x and y axes 20MeV/channel
 - few events stop in DSSSD#2
 - most events lower Z and A - fission fragments?

Attachment 23 - per DSSSD per pixel HEC-LEC time difference 4.096us/channel
 - events observed to <<100us

Attachment 24 - per DSSSD per pixel HEC-LEC time difference (1s/channel) versus LEC energy (20keV/channel)
 - alpha events long lived 
 - some evidence of effect of on spill deadtime in implant-decay correlations (cf. S100 and S505)

Attachment 25 - per DSSSD implant and decay event p strip - n strip time difference (2us/channel)
 - wider distribution for implant events as expected due to number of ASIC active channels in implant events
 - most decay events +/-2us - lower ASIC occupancy for decay events so most events will be from same (or adjacent) clock cycle
