Data Management
Data storage
All types of data (raw, reco, analysis) should be stored in CASTOR (see
more instructions). TOTEM's base directory is
/castor/cern.ch/totem/
. For each data type, there is a dedicated directory:
raw |
/castor/cern.ch/totem/LHCRawData/ |
reco |
/castor/cern.ch/totem/offline/Reco/ |
analysis |
/castor/cern.ch/totem/offline/Analysis |
For short term work, there is a temporary AFS space allocated at
/afs/cern.ch/exp/totem/scratch
. The structure is similar to the one of CASTOR space:
raw |
/afs/cern.ch/exp/totem/scratch/data |
reco |
/afs/cern.ch/exp/totem/scratch/offline/Reco |
analysis |
/afs/cern.ch/exp/totem/scratch/offline/Analysis |
For both, CASTOR and AFS spaces, the subsequent directory structure shall be
year/subsystem
. The
year
obviously is like
2010
, the
subsystem
may be one of these:
RP, RPT2, T1, T2
Conditions data storage
For RP positions, BLM and BPM data, etc. there is a
temporary storage space allocated on AFS
/afs/cern.ch/exp/totem/scratch/data/RP/<date>/conditions
Eventually, these data shall be saved on CASTOR
/castor/cern.ch/totem/LHCRawData/<year>/ConditionsData/<date>
year
is for example
2010
,
date
is the data-taking date in format
yyyy_mm_dd
. If the data-taking spanned over two calendar days, use e.g.
2010_08_04-05
. If there are several data-takings within the same days, use
_1
,
_2
, ... suffixes.
Alignment data
Alignment data can be found in
/afs/cern.ch/exp/totem/scratch/data/RP/<date>/alignment
There are usually several subdirectories with different versions of the alignment. Each directory shall contain a
description
file that gives information how the alignment has been obtained.
