SPEFO is a stellar spectra analysis program created by the Astronomical Institute of the Academy of Sciences of the Czech Republic. An rvr file stores stellar spectra analysis data for use by the program.
The RVR format is an application-specific data format associated with SPEFO rather than a general-purpose exchange format. Its contents are intended to be interpreted by SPEFO as part of the program's analysis workflow.
SPEFO is a legacy Microsoft MS-DOS application, so this file format may be difficult to use on current systems without a suitable MS-DOS environment. It is not generally used as a modern standalone data format.
Open the rvr file with SPEFO. SPEFO was made for Microsoft MS-DOS, so a compatible MS-DOS environment may be required on a modern computer.
