LUCI1 Spectral Flats with N375

The LUCI1 N375 grating flats show a distinct illumination pattern.  Below is an example taken with the G210 at 1.66 and H filter and LS_0.5arcsec longslit.  This pattern is not apparent with the N1.8 camera.  The exact source of this illumination pattern is currently under investigation. This illumination pattern became apparent after the LUCI1 camera swap several years back. The camera is slightly undersized relative to the old one and was installed with a custom mount.
