CIRPASS software specification

These pages deal with the data reduction and analysis software. The main point of these pages is to provide a guide for ourselves as to what we require our software to do and how it will all fit together. They are on our public pages as there are various groups writing similar code and therefore they might want to look at our ideas and vice versa.

These pages are still changing as our software is written.

You may find the glossary of data reduction terms useful.


The data reduction software runs in IRAF.

We are writing our own data reduction software. We are using a mixture of existing IRAF tasks and our own C programs.

We are not writing data analysis software as we do not have sufficient manpower. We are involved in the Euro3D group, which aims to bring together European groups working with 3D instruments to write common data analysis tools.
