- New release on 2007/08/17
-
-AliTRDmcmSim is now stably working and zero suppression function seems ok.
-From now, the default version of raw data is set to 3 in AliTRDfeeParam.
-
-The following internal parameters were abolished because it is useless and
-made trouble:
-
- fColOfADCbeg
- fColOfADCend
-
-GetCol member was modified accordingly.
-
-New member function DumpData was prepared for diagnostics.
-
-ZSMapping member function was debugged. It was causing crash due to
-wrong indexing in 1 dimensional numbering. Also code was shaped up better.
-
-*/
-
-/*Semi-final version of TRD raw data simulation code with zero suppression (ZS)
-similar to TRD FEE. ZS is realized by the class group:
-
- AliTRDfeeParam
- AliTRDmcmSim
- AliTRDrawData
-
-AliTRDfeeParam has been modified to have more parameters like raw data
-production version and so on. AliTRDmcmSim is new class and this is the core
-of MCM (PASA+TRAP) simulator. It has still very simple function and it will be
-another project to improve this to make it closer to the reall FEE.
-AliTRDrawData has been modified to use new class AliTRDmcmSim.
-
-These modifications were tested on Aug. 02 HEAD version that code itself
-compiles. I'm sure there must be still bugs and we need testing by as many as
-possible persons now. Especially it seems HLT part is impacted by problems
-because some parameters were moved from AliTRDrawData to AliTRDfeeParam (like
-fRawVersion disappeared from AliTRDrawData).
+#include <iostream>
+#include <iomanip>
-In TRD definition, we have now 4 raw data versions.
-
- 0 very old offline version (by Bogdan)
- 1 test version (no zero suppression)
- 2 final version (no zero suppression)
- 3 test version (with zero suppression)
-
-The default is still set to 2 in AliTRDfeeParam::fgkRAWversion and it uses
-previously existing codes. If you set this to 3, AliTRDrawData changes behavior
-to use AliTRDmcmSim with ZS.
-
-Plan is after we make sure it works stably, we delete AliTRDmcm which is obsolete.
-However it still take time because tracklet part is not yet touched.
-The default raw version is 2.
