RoI sizes used by the LVL2 system

Number of ROBs, size of event fragments :
Pixels : 62 ROBs * 1200 bytes
SCT : 92 ROBs * 1600 bytes
TRT : 256 ROBs * 600 bytes (low luminosity), 800 bytes (high luminosity)
Em calorimeter : 754 ROBs * ~ 1600 bytes (was : 738 ROBs * 2000 bytes)
Hadron Calorimeter : 98 ROBs * ~ 1600 bytes (was 2000 bytes)
µ-trigger : 48 ROBs * 380 bytes
µ-precision : 192 ROBs * 850 bytes
(NB all results for 738 ROBs for em calorimeter and 2000 bytes fragment sizefor both calorimeters, improved mapping for em calorimeter will result in smallerdifference between lower and upper limit for rates and data volumes)

Present results
No analysis of jets in tracker
TRT scan leads to requesting all datafrom SCT and pixels
Processing parameters and process models asagreed on in January meeting and as documentedin MWD
Accept decisions combined with reject decisionsin blocks of 20 decisions multicasted to all ROBIns
TRT, SCT and pixel scan and missing energy RoI requests multicasted
NB : Processing sequence for em RoIs to be modified, resultingin reduction of RoI request rate for and of volume of data to besent by hadron calorimeter ROBIns (reduction factor probably ~ 6)
