1) If the flat lamp on the outside of the IGRINS cal unit is staying on, take a flat image to reset the power state in the control software. Or press the power button inside the electronics cabinet.
2) If the auto-guide software is over-correcting and the source is oscillating around the slit, change the scaling factor in the offending direction.
3) If icsrun start-up routine fails to start and reports an error with the logging routine then reset permissions with:
igrins% sudo sh icsrun
4) When the Instrument Control Computer (ICC) has the screen freeze, look for an unresponsive script in the background:
command-option-escape
5) If you need to reinitialize the detector than follow the same steps as initialization in the Full Startup Procedures, except do not reload the JADE2 firmware.
6) Growling/Gurgling sounds from the coldhead may mean that the power cable has been compromised and needs to be replaced. More information available here.
7) If 'Go R' fails then first check that the TCS says 'On Target'. If the target is very bright then the centroid will fail and 'Go R' will fail. Moving the field manually, using the buttons above 'Go R' can sometimes fix this issue. Otherwise, please restart the control software.
