Clicking on the three vertical dots beside a subsystem displays a drop down list of further subsystem status info, as can be seen below "Dome" and "Rotator 1" in the central panel of the screenshot above. The ethos behind the colour coding of subsystem status is as follows:
*'''Green''': a subsystem or state is either selected (e.g. in the screenshot above, the telescope is tracking at the sidereal rate, and the SHOC instrument is selected), or is in the correct state for observing (e.g. mirror covers open, dome shutters open, telescope tracking, dome tracking, rotator 1 (SHOC) tracking).*'''Orange''': a subsystem is in an inappropriate state for observing. In the screenshot above, Rotator 2's indicator is orange, which is acceptable because SHOC is mounted on Rotator 1, so only Rotator 1 needs to track with the telescope. If the mirror covers or dome shutters were closed, their indicators would turn orange; likewise if the lights were switched on their indicator would be orange.*'''Blue''': a parameter that has a numerical value but no right or wrong state is indicated in blue, e.g. azimuth or airmass.
