This was not corrected in the reported data. It is expected that this was due to the internal pen-ray lamp source. The noise in flight is of unknown. Beginning on 140915, the averaging time on the 49i was changed from 4s to 8s in an attempt to smooth out the noise. Reduction in noise was observed, but still greater than expected noise.
