== Change Log ==
*'''3 August 2017:''' Completed extensive testing of various gratings (particularly G7) in order to characterise the ghosting issues reported previously.
*'''29 July 2017:''' Moved the SpUpNIC utility panel to improve the routing of the cables and air hose for the pneumatics to reduce the pointing restrictions in the south east. New software limits will soon be implemented to take advantage of the increased clearance between the spectrograph and the north pier.
*'''10 April 2017:''' G7 replaced with an almost identical new one that does not have fingerprints or scratches! The blaze of the new one is at 5000A, rather than 4600A, since the latter is no longer available from the manufacturer. The 5000A blaze is also a better match for the peak response of this CCD.
* '''30 March 2017:''' New functionality added to the GUI for the rear-of-slit (Lodestar) camera to allow background subtraction. There is now also a slider bar to adjust the brightness of the display, this works best with background subtraction applied.
