PILOT RECORD
DANA blocklet(8.0)
+18 DELANA tagging bits:
bit 27 = 1 if the event passes the pre-filter
PILOT RECORD
DANA blocklet(8.2)
+1 Wordcount (23)
+2 Identifier (bits 1- 4) (8)
Error code (bits 5-32) (Usually FF10)
+3 Sub-identifier (2)
+21 DELANA Event-filter results:
bits 1 : event passes Super Team 1 selection
2 : event is single tagged gamma/gamma
3 : event is anti-tag gamma/gamma
4 : shower in HPC or FEMC with E > 5 GeV
5 : flagged as calibration event by DELANA
6 : soft event for degenerate searches 1
7 : single lepton event
8-12 : 'Hadronic' event selections from THADR 1-5
13 : soft event for degenerate searches 2
+22 DELANA calibration tag details:
bits 1 : collinear energetic tracks or showers. (mumu , ee)
2 : back to back low multiplicity jets (tautau)
3 : gamma/gamma ---> lepton/lepton
4 : single electron (old tag not accepted by filter)
5 : old Compton tag (old tag not accepted by filter)
6-7 : Compton tag (barrel)
8 : Compton tag (forward)
+23 Wordcount (23)
IMPORTANT: if you want to access to the events selected with the expected 1998 criteria then
you should run only on events satisfying the following test on the DANA pilot record banks (8.0) and (8.2):
EXTERNAL DELSEL
LOGICAL DELSEL
IF (DELSEL()) ---> The event is accepted !!
