Standalone calibration
The standalone calibration is performed on each of the LDCs assigned to the SPD (presently there are 8 LDCs). The table below shows the directory and file structure - in black - where the DA is running for one of these LDCs. In violet are some DAQ database IDs, in green the FXS IDs, in blue the run types are given for those scans that may produce output files inside the directory, and with red text it is indicated if the files in a directory should be kept persistently over different scans. Below the tables some descriptions of the files are given.

Physics run calibration
The physics run calibration is performed on one of the monitoring machines on the DAQ network. The table below shows the directory and file structure - in black - where the DA is running. In violet are some DAQ database IDs, in green the FXS IDs, in blue the run types are given for those scans that may produce output files inside the directory (in this case always PHYSICS of course), and with red text it is indicated if the files in a directory should be kept persistently over different runs. Below the tables some descriptions of the files are given.

File descriptions (alphabetically)
FILE NAME
|
DESCRIPTION
|
|
dcsConfig.tar |
This is a tar file that will be copied to FXS. It contains all the "dcsConfig_run_X_eq_X.txt" files inside the directory "./calibResults/ScanDCSConfigToFXS/". They carry settings for the DCS configuration database. |
|
dead_phys.tar |
This is a tar file that will be copied to FXS. It contains all the "SPD_Dead_X.root" files inside the directory "./calibResults/DeadToFXS/". They carry the dead pixels for updating of the OCDB. |
|
FXSids_runXXXX.txt |
This is an ascii file that will be copied to FXS. It contains all the ids of the files that are copied to the FXS (except its own and the id for files going to DCS). Its purpose is to spot errors during preprocessing. |
|
noisy_phys.tar |
This is a tar file that will be copied to FXS. It contains all the "SPD_Noisy_X.root" files inside the directory "./calibResults/NoisyToFXS/". They carry the noisy pixels for updating of the OCDB. |
|
noisy_scan.tar |
This is a tar file that will be copied to FXS. It contains all the "SPD_Noisy_X.root" files inside the directory "./calibResults/ScanNoisyToFXS/". They carry the noisy pixels for updating of the OCDB. |
|
perm_noisy.txt |
When the DA is started (at the end of the calibration run), this configuration file is fetched from the DAQ database. It contains a list of noisy pixels, that you always want to put noisy, no matter what. This could for instance be useful whenever the noisy pixel scan for some reason cannot find a noisy pixel. The pixels are put in the text file with values of eq,hs,chip,col,row - separated by space or tab. |
|
physics_params.txt |
When the DA is started, this configuration file is fetched from the DAQ database. It contains tuning parameters for the AliITSOnlineSPDphysAnalyzer class. |
|
ref_phys.tar |
This is a tar file that will be copied to FXS. It contains all the "SPDphys_run_X_eq_X.root" files inside the directory "./calibResults/NoisyReference/". |
|
ref_phys_dead.tar |
This is a tar file that will be copied to FXS. It contains all the "SPDphys_dead_run_X_X_eq_X.root" files inside the directory "./calibResults/DeadReference/". |
|
SPD_Dead_X.root |
File that holds the list of dead pixels for equipment X. It is kept in a TObject derived class called AliITSOnlineCalibrationSPD. Reading/writing from/to this type of file is easiest done via the class AliITSOnlineCalibrationSPDhandler. |
|
SPD_Noisy_X.root |
File that holds the list of noisy pixels for equipment X. It is kept in a TObject derived class called AliITSOnlineCalibrationSPD. Reading/writing from/to this type of file is easiest done via the class AliITSOnlineCalibrationSPDhandler. |
|
SPDcal_run_XXXX_eq_Y.root |
This is a so-called reference data file for equipment Y. It will be copied offline without further processing. |
|
SPDphys_dead_run_0_0_eq_Y.root |
Temporary reference file for equipment Y. When one run does not give enough statistics for a complete dead search, this file must be kept over several runs. |
|
SPDphys_dead_run_XXXX_ZZZZ_eq_Y.root |
This is a so-called reference data file for equipment Y. It is produced when the dead search has been completed, i.e. when enough statistics (runs) have been collected. The file is copied offline without further processing. |
|
SPDphys_run_XXXX_eq_Y.root |
This is a so-called reference data file for equipment Y. It is produced for every run. |
|
standal_params.txt |
When the DA is started (at the end of the calibration run), this configuration file is fetched from the DAQ database. It contains tuning parameters for the AliITSOnlineSPDscanAnalyzer class. |
