GBRAHMS modifications April 3, 2000

TPC geometry
The default geometry for MTP2 was not in accordance with the actual layout. E.g. the default setup had only 18 rows not 20. In addition the active rows were modified to reflect the actual instrumentation i.e.
TPC
Active Rows
Inactive rows
TPM1
1-12
-
TPM2
1,2,5,6,9-12,15,16,19,20
3,4,7,8,13,14,17,18
T1
1,2,3,4,7,8,11-14
5,6,9,10
T2
1,2,5,6,9,10,15,16
3,4,7,8,11-14
Additional a very small area of pad row 13 and 14 is also instrumented from pad#80-95 i.e. a single FEE card.
Gbr2c.f
The comis routine normally used to generate the .cdat files from the geant hits have had its entry points changed to be more logically. They are now
Gbrfile(<nameof file>) to open file
Gbrana to be called per event (analyze)
Grbend to close file properly
ZDC
The ZDC is by default off, since it the hit generation in the calorimeter adds a lot of CPU time per event in particular for event data (spectator protons and neutrons). It can be included in the usual fashion using the command set_tree zdc o .
New Components
A concrete floor has been added to description. By default it is off. You can include it by the set_tree flor o command.
Version No.
The new version is labeled 1.6.02.
Changes has been made over a peirod of time-commited to cvs today.
