* Please note that '''grating 13''' was a late addition and '''has not yet been incorporated into the software'''. This means that the SpUpNIC control software will not report that grating 13 is mounted, and will not know which science filter or arc lamp should be used - users will have to select these themselves based on the table above. The Quicklook software will not be able to identify the arc lines, nor necessarily plot them on a sensible scale - it may be necessary to zoom in on the spectrum in the Quicklook software to see the lines.
* Note that '''grating 6''' does not require an arc filter when centred on 5100A (grating angle of 13), which extends to ~6500A. If you need to include redder wavelengths than this (angles ~12 and below), you will encounter very bright arc lines from ~6800A and will need a '''BG38 filter''' in the arc beam to avoid saturation.
