Please see the attached plots, as the shutter closing time was varied from 20ms to 50ms.

The data is from the same spectrometer that Mike has, with the alignment that we shipped it with.

I apologize, the integration time is normally saved in the header file.  I will get the software team to add that for the future.  The integration time for that data is most likely 10 ms.  We set the shutter close time and shutter open time to 100 and 20 ms, respectively.  These numbers were determined experimentally in order to avoid the smearing artifact.  I still suspect the shutter close time to be responsible for the shoulder you see.

I am going to see if I can replicate the phenomenon on our system.
