Ken, there is a yahoo newsgroup dedicated to Roddier testing. It has many useful pointers on how to do the test (bottom line is you need a FITS file, and contrast and sharpening must not be manipulated in any way). There are even English versions of program itself, and latest versions are far more robust to input data variations (the original was painfully intolerant to any extra data in the FITS header, even to the order in the header itself, it required precise amount of defocus in both directions etc. etc. New versions from 2.2 onwards are far more civilised).
