I have finally produced an early version of something I have been meaning to do for a long time - a Python LM-63 file reader module. This is part of a larger project to update ies2rad.
The reader module is alpha. It will read and store data from all four versions of the IES LM-63 standard, with the exception of tilt data. If anyone is interested in trying this out, or has a project that might use it, please let me know!
