     Remarks:
     1) Source of EMCAL pedestal and zero-suppression is under discussion.
     2) EMCAL HV values for each APD are manually inserted via DCS, not known where to find them back.

     4) Calibration procedures for EMCAL calibration are available as macros using the full aliroot framework, need to be imp
     5) Number of coefficients for obtaining peak ADC value is under discussion.
     6) There will be a number of temperature sensors on Supermodules. The number and location is under discussion.

FMD Notes:
  1 Name changed to reflect actual contents

     2 Running conditions like oversampling, strips readout, zero suppression, etc. is normally set
       via DCS, and the DCS logbook will contain the set-points. However, in Yves' document
     3 Since I'm the one that know most about the FMD FEE these statements are not really
       objective :-) I'm not really too familiar with the DCS part of the system, but we plan to follow
     4 This data is controlled by the DCS, and as such does not require processing to extract.
       However, in certain cases, like the pulser gain calibrations, the DA may control these
5 Since the pulser gain calibrations require that we loop through the strips and through pulser
  values, we have to have some sort of sub-run. That can be done by letting the LDC control
6 This item really covers what in the TPC case is called 'Parameters of the FEE required for
  reconstruction ...' Hence, note (2) above applies here.
  DCS access - offline has access only to DCS archive DB, curently no access to

  DAQ - offline has access to raw data and DAQ logbook, but no acccess to LDC or GDC

  OCDB - Calibration parameters are stored in the Offline Calibration DB. The data used




  Use case 1:                 online creation in DAQ
  Calibration parameters are computed online in the DAQ LDC/GDC/Monitoring machines
  Results are made available as ROOT files in the DAQ FES
  The path of these files together with the start and end of run timestamps is written in
  At the end of the run additional processing may occur controlled by the ECS
  Upon notification by the ECS, the SHUTTLE queries the DAQ Logbook for file name
  It stores the files into the CERN storage and adds an entry (run validity and unique



  Use case 2:                 online creation in HLT
  Calibration parameters are computed online in the DAQ LDC/GDC/Monitoring machines
  Results are made available as ROOT files in the DAQ FES
  The path of these files together with the start and end of run timestamps is written in
  At the end of the run additional processing may occur controlled by the ECS
  Upon notification by the ECS, the SHUTTLE queries the DAQ Logbook for file name
  It stores the files into the CERN storage and adds an entry (run validity and unique




  Use case 3:                 online creation in DCS
  Calibration parameters are computed online in the DCS farm from dedicated data
  Results are made available, as ROOT files, in the DCS FES
  The path of the produced files together with the start and end of run timestamps is
  At the end of the run additional processing may occur controlled by the ECS
  Upon notification by the ECS, the SHUTTLE queries the DAQ Logbook or the

Use case 4:               parameters monitored by DCS
DCS monitored parameters are stored in the DCS Archive DB
At the end of the run additional processing may occur controlled by the ECS
Upon notification by the ECS the SHUTTLE queries the DAQ Logbook for the start
The SHUTTLE pre-processors evaluates the parameters, creating the ROOT files
It stores the files into the CERN storage and adds an entry (run validity and unique




Use case 5:                   FEE config file
The FEE parameters are fed to the electronics either trough the DCS or through the DAQ
DCS:
files are stored in the DCS Configuration DB and on the DCS file exchange server, the
notification is done through the DCS Archive DB

DAQ:
files are stored directly in the DAQ FES and their name registered in the DAQ Logbook
(back to Use Case 1)
At the end of the run additional processing may occur controlled by the ECS
Upon notification by the ECS the SHUTTLE queries the DCS Archive DB for timestamps and
