If you encouter the error "another instrument with same name already exists", you probably have built one settings with multiple oifits files. It is actually one limitation of the internal engine which should be fixed soon. To be able to fit such settings files, you actually need to modify manually the name INSNAME keywords of each given files. It must be done in all the OI_VIS, OI_VIS2, OI_T3 plus the corresponding OI_WAVELENGTH tables. Each values must be different to be fitted by LITpro. Apologize for the actual limitation. We are working on this issue for the next releases.

An alternative is to merge multiple oifits files into a single file. This can be done using the oifitslib software available at the following address: ftp://ftp.mrao.cam.ac.uk/pub/jsy1001/oifitslib/oifitslib.tar.gz

During the last IAU conference in August 2009, the Optical and
Infrared Interferometry Commission (C54) raised a few questions
(get the whole story on http://olbin.jpl.nasa.gov/iau/2009/index.html).

One of them was :
"Is there a command line tool to throw at an OIFITS file to do a
simple uniform disk fit?"

Well, now, there is. Just "call Iper"

This simple tool allows you to rapidly see if your set of squared
visibilities is fitted or not by a uniform disk.
