/* Safety */
Below is a screenshot of the main "Controls" tab of the TCS, where everything required for routine observing is located. There is one other tab, for more rarely used "Advanced" functions. The Controls tab is split into four main panels: control of the telescope and instrument selection on the left; status of each in the middle; time and position information on the upper right; and important buttons that need to be easily accessible on the bottom right.
It is important to note the '''Emergency Stop''' button, on the lower right of the TCS display. It is always visible on both tabs, and will stop the motion of the dome, shutters, telescope, rotators and secondary and tertiary mirrors. It will not stop the guider XY-slides. The Emergency Stop button should be clicked if anything that is moving is going to cause a hazard. Once clicked, the Emergency Stop button will be toggled to read '''Reset''', and you must ensure that it is safe to reset all the subsystems before pressing this button to continue.

The '''Startup''' button is not a "power-up" button, as everything should be powered up at all times. The Startup button should be used only when you intend to open up to observe, as it runs a script that performs the following tasks in this order:
# Take remote control of the dome
# Switch off the fluourescent lights
# Switch on the slew lights
# Open the dome shutters
# Open the mirror covers
# Unpark the telescope so it can be moved
# Set the dome to track the telescope
# Switch off the slew lights
Once the Startup procedure is complete, the button will read '''Shutdown''', and should be used to close everything at the end of observing. The shutdown script essentially reverses the Startup procedure:
# Turn on the slew lights
# Close the mirror covers
# Close the dome shutters
# Park the telescope at alt=50, az=90
# Park the dome at az=270
# Switch off the slew lights
Control of the dome is not given up, but it can be "taken" using the lockout in the dome.
'''If you don't want to run the full Startup procedure''' (e.g. because it's daytime), but do need to interact with the telescope, the individual commands...
***************how much of the controls tab works without startup?****
From the '''Advanced''' tab, you can do the following:
* Take control of the dome (you don't need this to operate the slew lights)
* Switch on/off the fluorescent lights and slew lights
* Open/close the dome shutters and mirror covers
* Slew the telescope to a given alt-az position *******does it start tracking?? If so, warn user
* Start/stop the telescope tracking
* Park the telescope (alt=50 az=90)
* Rotate the dome to a given azimuth
* Park the dome (az=270)
* Toggle the motors of the altitude drive, azimuth drive, secondary mirror, tertiary mirror or the rotator on which the currently selected instrument is mounted between auto and manual mode. The motors should be in auto mode for normal operations, anything in manual mode will not work. '''Never select manual mode for any motor.'''
'''The typical focus value for SHOC is ~2000.'''
