Ignacio, If you read the IES file in a text editor, you will see the
bottom portion of the file is mostly 0 values, but with several 0.1 and
0.2 mixed in.  This is either erratic values in the photometry, or
demonstration of actual light leaks from the fixture as it was measured.
It does not appear to be a result of any Radiance parameters.
