MSDP WorkshopPRACTICAL SESSION
P. Maeght, P. MeinN. Mein, M. Lafon, N. MeunierT. Roudier
MSDP Workshop, Tarbes, 18-20th January 2006
Directories oceanide
/data3/DPSMWS/day/ : raw sequences /data4/groupX/ (one dir. / group, X=1,2)
auto0503/ : code for THEMIS observations until 2004
auto0601/ : code for THEMIS observations since 2005
dalsa/ : code for VTT docdpsm/ dpsm_form/
Results will be in auto0503/ or auto0601/
Directories gaia
/baie1/DPSMWS/day/ : raw sequences /baie1/groupX/ (one dir. / group, X=3,4)
auto0503/ : code for THEMIS observations until 2004
auto0601/ : code for THEMIS observations since 2005
dalsa/ : code for VTT docdpsm/ dpsm_form/
Results will be in auto0503/ or auto0601/
+ 0503
VTT processing
Similar algorithm but manual (no msdpauto, no sequence.par)
editing of dalsa.pro, ms.par (file time …)
Start ms1 directly
In autoXXXX/
The msdpauto (IDL) will : create directories for the results
dir_date_seqnum_camnum/ copy the code in it go to this directory build the ms.par start the fortran code put the results thereCopy the resulting g* file (geometry) in the
upper directory in case useful for another sequence
Goto /data4/groupX/ or /baie1/groupX/ Goto the autoxxxx/ corresponding to the
sequence Make the sequence.par if not provided
manually (see example in /data3/DPSMWS/sequence_model.par)
automatic with the BASS2000 interface To get bs + camera number : edit fits file
x=mrdfits(/data…./*.fts’,ran=[0,0]) (WARNING 2004 : 2 cameras / line)
Depending on the case : start msdpauto, « /dir_data/ » start msdpauto, « /dir_data/ », /no_fort, modify
ms.par then start ms1 other procedure if indicated
File vizualization
How to process a sequence
File vizualisation
IDL : x=readmsdp(‘file’) (q* or p* file) check the image order in the file tvscl,x(*,*,i) ; plot… (cut) etc.
When using the BASS2000 interface : choose q or p, and « Voir DEP » : equivalent to tvscl
Postscript files : kghostview file.ps ; or « Voir PS » in the BASS2000 interface
Rep auto
Makesequence.par
msdpauto
Edit sequence.par if modificationIf modif ms.par
Categories of sequences
Good sequences (THEMIS, VTT) Sequences with interruption during
the processing Sequences providing maps or
profiles showing problems (visual verification)
For each sequence
Date, sequence number Line(s) Volume Time to process (for 100% CPU time on
our machine) Problem if any, illustration before / after
To reduce processing time after transformation b3 to individual files
: tob1, tob2 in ms.par ; or nob1, nob2 (msdpauto should have been started with /no_fort)
stop at « q » step (qp = 0 in sequence.par) for quicklook only (no profile)
keep only one stokes if several are observed (qv, nq in sequence.par) ; see SEQ_STOKES in fits header
Beam exchange : nqseul = 7, 8, 9 in ms.par (otherwise 0)
