This is a Python/Qt5 port of the RaveSpan analysis tool developed by Dr. Bogumił Pilecki at the Nicolaus Copernicus Astronomical Center of the Polish Academy of Sciences.
It is far from complete. I have it partially working under Python 3.10, PyQt5 5.15.7, however it is failing to find files and intermittently crashing. This could be operator error, or bugs introduced during porting.
