Input data organization

The commands below apply to the csh family of shells (i.e csh and tcsh) and should be adapted for other families of shells. In order to set up a proper environment, you first have to create an analysis directory (e.g spi_data_rep) and "cd" into it:

mkdir spi_data_rep
cd spi_data_rep
setenv REP_BASE_PROD  $PWD

This working directory will be referred to as the ``REP_BASE_PROD'' directory in the following. All the data required in your analysis should then be available from this ``top'' directory, and they should be organized as follow

scw/

: data produced by the instruments (e.g., event tables) cut and stored by SCWs,

aux/

: auxiliary data provided by the ground segments (e.g., time correlations),

cat/

: ISDC reference catalogue,

ic/ 

: Instrument Characteristics (IC), such as calibration data and instrument responses,

idx/

: set of indices used by the software to select appropriate IC data,

and all data resulting from your analysis will reside in an obs branch (in that same directory), which will be created by the first analysis step (og_create, see below). Part of the above input data may already be available on your system. You can either copy the data to the relevant directory or create soft links as follows:

ln -s directory_of_ic_files_installation/ic 
ln -s directory_of_ic_files_installation/idx 
ln -s directory_of_cat_installation/cat 
ln -s directory_of_local_archive/scw 
ln -s directory_of_local_archive/aux

The different ``directory_of_...'' can be all the same location. For example, if you are logged on the ISDC network and have a direct access to the revision 3 ISDC archive, these links become

 
ln -s /isdc/arc/rev_3/ic
ln -s /isdc/arc/rev_3/idx
ln -s /isdc/arc/rev_3/cat
ln -s /isdc/arc/rev_3/scw
ln -s /isdc/arc/rev_3/aux

Alternatively, if you do not have any of the above data on your local system, or if you do not have a local archive with the scw/ and the aux/ branch available, follow the next section instructions to download data from the ISDC WWW site. If you do have already the data available on your system, you can skip next section () (you need however to build a list of ``DOLs'' for your analysis that you can either produce using the archive browser or editing it``by hand'').
