*(5) Think about optimal slit size — 1.5” min, could be up to 2”, could also consider stepped slit — these are laser cut, and we could request more than one (Amanda & Hannah)
*(6) Thinking about .fits header information for compatibility with data reduction pipeline, and how to integrate TCS with instrument to allow automated acquisition (Carel)
 
== SHOC/SPRAT hybrid ==
* Point was raised that (rather than comount SHOC and this new spectrograph) we could use an iXon camera in the SPRAT system, add filter wheels, and effectively use it as SHOC when the slit, grating, and prisms are out of beam. The iXon has 1024 x 13-micron pixels as opposed to the iDus 1024 x 26-micron pixels. A test was performed at LT in the week of 15 Dec., in which the 85 mm f/1.8 camera lens was swapped out with a 50 mm Nikon f/1.4. The result from an arc was 7.70 Å/channel, central wavelength 6009.04 Å, range 4073.64 – 8018.33 Å. This range could be tweaked by tilting the camera slightly.
