If you mean that the function should be tested with more data and should also work with other input such as ``[power] Power unit of WAVELNTH in meter``, ``(integ) UNIT OF WAVELNTH`` or ``Observed wavelength (nm)``, then I'm totally on your side and say that's something that's still missing. I was quite busy with uni this week and will be until Wednesday (written exam). I think I can fix this in the middle of the next week. Sorry for the late reply.
