I wrote several IDL programmes for reducing, visualising and modelling interferometric data obtained with MIDI. Many programmes require the AstroLib package (http://idlastro.gsfc.nasa.gov/) or the MIA+EWS package (http://www.strw.leidenuniv.nl/~nevec/MIDI/) to be installed. The first is actually contained in the latter. A more detailed description of every routine is contained along with the code in the individual files which can also be downloaded at http://www.korowa.de/sci/downloads.html (link is pending to change soon, just in case I forget to adjust this reference :-). A brief description of the routines follows below. If you have any suggestions for improving the code, please contact me.
