CMON

CMON is CLAS Online Data Monitoring program. It does real time event reconstruction using old 'sda' program rewritten to C and modified for multithreaded environment.

Road Maps

Road maps are used by Pattern Recognition. To generate road map following command must be used:

Calibration Constants

Calibration constants are stored in offline database. It can be accessed at this link.

Calibration constants must be extracted from offline database and stored in a form of map files to be used by CMON. To extract information from database to maps, db2clonmap.pl script must be used. It can be run with following parameters:

db2clonmap.pl runMin=<minimum run> runMax=<maximum run> \
      [system=<system name>] \
      [skip_run_control=<non-zero to skip RUN_CONTROL system>] \
      [runIndexTable=<run index table name>] \
      [time=<date/time of validity>] \
      [hostname=<db server hostname>] \
      [quiet=<non-zero to supress printout>] \
      [help=<non-zero for usage message]

For example, to extract tagger calibration parameters goto $CLON_PARMS/Maps and run

db2clonmap.pl system=TAG_CALIB runMin=1 runMax=1000000

it will create subdirectory Maps_1-1000000, create TAG_CALIB.map inside and fill it up.

Default runIndexTable is RunIndex. For some run periods calibration constants are stored under different runIndexTable name, for example for g8b runIndexTable was calib_user.RunIndexg8b. In that case use command

db2clonmap.pl system=TAG_CALIB runIndexTable=calib_user.RunIndexg8b unMin=1 runMax=1000000
db2clonmap.pl system=SC_CALIBRATIONS_V2 runIndexTable=calib_user.RunIndexg9 runMin=1 runMax=1000000

To extract entire database run following command (it is important to use 'skip_run_control=1', otherwise it takes forever)

db2clonmap.pl skip_run_control=1 runMin=1 runMax=1000000

After it finished, move all *.map files to $CLON_PARMS/Maps.

Calibration databases can be dumped in a form of ascii file using following procedure:

$CLAS_TOOLS/caldb/caldb_show_constants_run.pl s=TAG_CALIB ss=tag_t i=ci r=40000 > /home/boiarino/z123

JUST FOR INFORMATION, DO NOT DO THAT: To white it back remove first two lines and type:

$CLAS_TOOLS/caldb/caldb_write_and_link.pl s=TAG_CALIB ss=tag_t i=ci min=40000 max=50000 ci="test1" f=/home/boiarino/z123
