-This cools the camera to -60 C. You can read the current temperature from the pavo server. As of 2014, we are doing air cooling (PAVO is no longer hooked up to water cooling). Because of this, the minimum gain setting should be 170 for almost all targets (not 150). If you leave the pavo computer on and the camera plugged-in, then you don’t have to do anything until a PAVO run is over. At the end of the run, type "coolon 0" into the server and it will raise the temperature to 0 Celsius. Once it gets to about 0, it is "safe" to switch anything and everything off without damaging the CCD. +This cools the camera to -50 C. You can read the current temperature from the pavo server.

 \\  Previous Notes: When PAVO was hooked up to the water cooling, the camera was cooled down to -70 C. [CCD Cool] had to be turned on through the power gui for this to work. The fan is also on, so nothing should break if CCD cool isn’t on; it will just stop at about -55C and not go any lower. The gain numbers in the current mode only apply to this temperature. \\  Previous Notes: When PAVO was hooked up to the water cooling, the camera was cooled down to -70 C.
