I guess so.  Thanks for catching that.  I checked and it seems that the only withFlux calls in test_chromatic.py are for the SED class.  Nothing for constructed ChromaticObjects.  I'll add a few tests to make sure this function gets touched.

I guess it's a good thing I have that particular typing problem -- I constantly notice myself typing ration.  It seems my fingers don't want to stop after typing "tio" at the end of a word.  :)  But this time at least it led you to discover a hole in our test suite.
