ITR Software Changes

All source code for the named versions is available under CVS (CVSROOT=/afs/desy.de/group/hera-b/ITR/cvsroot). The easiest way to get the sources is to use xcvs (for example, xcvs get ITR_marvin 6-3)

ITR_silraw

Version 6-2

• Renamed all source files to begin with ITR_
• Incorporated Arnd Lange's changes to use ITR sparsification
• Speed-up in ITR_silraw_get_superlayer

Version 6-3

• Reading back pseudo-SLB blocks filled with sparsified event information reimplemented

Version 6-4

• Handle case of too large sparsified blocks more gracefully
• Prescale some warning messages
• Code cleanup

Version 6-5 (Feb 5, 2001)

• Switch off reporting of bad/missing FEDs by default (set parameter fed statistics period to 0)

Version 6-6 (Mar 4, 2002)

• Throttle error messages and debugging output even more.
• Support for extra-long pipeline-length of Helix 3.1A added.
• Use ITR_leda_FED_getDVOffset() to get datavalid offset individually for the chips of each chamber.

ITR_marvin

Version 6-2

• Renamed all source files to begin with ITR_
• Incorporated Arnd Lange's changes to use ITR sparsification

Version 6-4

• New baseline subtraction, noise and pedestal following (à la marvin3-3)
• Re-introduced condensed cluster format 3 for use with online sparsification:
  

  
  	    unsigned short chamberid;  // internal chamber id (key into ITR_Chamber)
  	    unsigned char  charge;     // max (cluster_charge , 255. )
  	    unsigned char  sn4;        // max ( 4 * signal / noise,  255 )
  	    unsigned char  width;      // max (cluster_width , 127 )
  	    float          cog;        // centre of gravity
  	

Version 6-5

• New cluster format 5 includes first strip of cluster:

  
  	    unsigned short chamberid;  // internal chamber id (key into ITR_Chamber)
  	    unsigned char  charge;     // max (cluster_charge , 255. )
  	    unsigned char  sn4;        // max ( 4 * signal / noise,  255 )
  	    unsigned short swidth;     // ((start & 0x7FF) << 5) | (bwidth & 0x1F)
  	    float          cog;        // centre of gravity
  	

  First wire (start) is unpacked into cluster->first
• Handle too large sparsified data blocks correctly (treat SLB_SUBHDR.length as (unsigned short))
• If setup data base is updated and re-read, ITR_marvin needs to be re-initialized (e.g. in the SLP). This can now be done without leaking memory (function ITR_marvin_cleanSetup()).
• Code cleanup

Version 6-7 (Feb 5, 2001)

• Bug fix for the unpacking of the cluster width in cluster format 5

Version 6-12 (Mar 4, 2001)

• The meaning of chip->chanstat has slightly changed to accommodate the software masking of bad channels:

  > 0	Channel OK
  = 0	Channel not connected
  < 0	Channel masked by software

• Support for extra-long pipeline of the new Helix 3.1A added

itrleda

Version 6-6

• (Re-) Introduced the possibility to keep information on different database servers:

  Data	Example	Default Server	Steering Parameter
  static data	mapping of chips to chambers	/ITR_Setup	itrleda setup database
  alignment data	displacements and rotations	/ITR_Align	itrleda align database
  monitoring data	noise per channel	/ITR_Setup	itrleda mon database

Version 6-7

• The complete database tables can be read into a collection of c structures. Relations are preserved. This is intended to be used with CNA for transport of the data bases to the SLT/4LT nodes. For this a collection of helper functions exist now:

  ITR_leda_XXXX_structFromTable() loads the database table XXXX currently residing in memory into the corresponding structure.

  ITR_leda_XXXX_tableFromStruct() removes all entries of XXXX and reads in the table from the structure.

  Finally, ITR_leda_RelationsFromStruct() fetches all relations present in a collection of structures. All structs must be filled and all tables must be created in memory before.

• Reading in of alignment table ITR_Align is now separate from the rest. Function ITR_leda_fetch_alignment (char *dbase, int major, int minor) assumes that the other relevant structures are already filled and establishes the relations between Leda tables. ITR_leda_startprogram() already calls ITR_leda_fetch_alignment() instead of doing the work itself.

Version 6-8

• General code cleanup
• Move reading of individual tables to functions itrleda_fetch_TABLE

Version 6-13

• Enhanced support for CIF formatter
• Introduced new table ITR/DVOffset. Use together with the functions ITR_leda_FED_getDVOffset(fedid) and ITR_leda_getDVOffset(chamberid)
