Changes
/* Setting up the grating */
* The software knows which order-blocking filters should be used with each grating, but it is still a good idea to check that the correct filter is selected (refer to the table above). If necessary, select the required filter from the drop-down menu at the bottom of the ''Instrument Setup'' pane and click ''Go''.
* 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.
