I understand... but don't blame me if it hurts your head ;) The class is here: http://python.pastebin.com/gPpep50Y
The function is here: http://python.pastebin.com/faK0vZ8U The issue is with the 'reflectance' method of the FlightData class (line 76). You can see in the class definition I now just add reflectance to self, but before I was trying to return it, and in the function (line 38-40) I was calling the method to get the array. On Ipython it worked fine to call the method and get a refl array. The array worked as expected (ie. refl.max(), refl.min() returned floats). But when I passed the same FlightData object to the function and called it inside it would not work. It would still return a numpy.ma.core.MaskedArray, but the max and min methods on the array returned empty values, which caused my function to crash.
