How to install the EIS QL and DA Software:

  1. Installing SolarSoft

    The EIS QL and DA software is distributed through SolarSoft (SSW). Solarsoft is a set of integrated software libraries (primarily in IDL) and databases that provide a common data analysis environment for solar physicists. It has a wide range of general IDL routines, as well as instrument specific ones for many instruments and space missions. Using SSW is highly recommended - both because of all the useful stuff in there, and it ensures that everyone uses the same (and updated) version of the EIS software package.

    Many institutions have SSW installed and updated regularly. If you are uncertain whether or not your workplace has SSW installed, you need to check wwith your local computer admin. Also, please make sure that the SSW package is updated regularly, preferentially every day.

    Your SSW installation need as a minimum the EIS, CDS and CHIANTI packages installed to work properly.

    If you need to install SSW yourself (e.g. on your laptop), please check the SSW website linked above and follow instructions from there. We have successfully installed SSW under Windows XP and Mac OSX, and can use our limited experience to assist you if necessary.

    Once SSW is installed, you need to make sure it is updated regularly. This is very important, otherwise you will eventually end up running an outdated version ofthe software, which could even (god forbid!) have bugs in it. The details on how to do this is described on the SSW webpage, and this is dependent on what operating system you are using. Again, we have some limited experience doing this and will try to be helpful towards a person in need.

  2. SSW Setup on your local machine - Unix (Mac OSX and Linux)

    Assume you have SSW installed and updated regularly. Now, you need to set up SSW so that it runs properly on your computer. This is again a procedure that will depend on the platform SSW is installed on. In what follows, I will describe the procedure for my laptop, running Mac OSX with tcsh Unix shell.

    If you are running tcsh, you should have a file called .cshrc on your home directory. I have the Solasoft installation under the ~/ssw directory. With this setup, I have the following commands in my .cshrc file:

    • setenv SSW ~/ssw


    • source $SSW/gen/setup/setup.ssw

    The first command sets up the SSW environment variable, and should point to the top diretory of you SSW installation. The second line lists the instrument packages you have installed and want access to, and the third command runs the SSW setup script.

    If you are running a different Unix shell, the commands may differ slightly and need to be put in another file (e.g. in the .bashrc file for bourne shell).

  4. EIS specific setup - Unix (Linux and Mac OSX)

    If the previous steps have been performed correct, you should now have a working set of EIS software to perform QL, calibration and data analysis on your data. The only thing left to get started then is to get acces to you data! There are several ways of accessing data. EIS data distributed through SSW, can be accessed using the 'eis_cat' program, described elsewhere. Here I will concentyrate on how to access data stored locally.

    In the following, I will assume that local EIS data is stored in a catalog named ~/solarb/eis/data/. To access these data, you may use a widget tool called In order for this program to work properly, you need to tell it where to start looking for data. This information is again, similarly to the SSW setup procedure, put in the .cshrc (or equivalent) file. In this case, add the following lines to the .cshrc file:

    • setenv EIS_INST "ITA-UiO"

    • setenv EIS_DATA ~/solarb/eis/data

    • setenv EIS_CCSDS_DATA $EIS_DATA/science/ccsds

    • setenv EIS_FITS_DATA $EIS_DATA/science/fits

    • setenv EIS_CAL_DATA $EIS_DATA/cal

    This sets up the environment variable "EIS_DATA", and the default catalogs for CCSDS (telemetry data), FITS data and calibration data.

  5. EIS setup procedure for Windows XP

    Will come soon....
