Tutorials for EUVI Data Analysis Software


Set your environment variable in your IDL startup file to: setenv SSW_INSTR "stereo secchi sbrowser"
Including these packages automatically also includes the path: $/SSW/package/mjastereo/idl/
which is needed for the EUVI data analsyis software described in the following.
On the following tutorials pages you can just click and copy the lines that contain IDL commands (orange color)
and drag them into your IDL window to execute them.

You need also access to the SECCHI database, which you have available at SECCHI centers (e.g., NRL, GSFC, LMSAL, ...), or alternatively you may download SECCHI data onto your local machine (e.g. through the STEREO science center at http://stereo-ssc.nascom.nasa.gov/data.shtml or trough the Virtual Solar Observatory VSO). The SECCHI archive is described in http://sohowww.nascom.nasa.gov/solarsoft/stereo/secchi/doc/scctree.txt (you can also get there through http://secchi.nrl.navy.mil/ , click on "SECCHI wiki" (lower left), then "4. Data Processing and Analysis" and then "Description of SECCHI Data Archive" (under SECCHI Data Management)). In the following example, the level-0 SECCHI data are available in the globally defined data directory DATADIR='$secchi/lz/L0/' (e.g., pointing to DATADIR='net/kokuten/archive/stereo/lz/L0' at LMSAL).
