Fringes in Cross Profile of Guider

If fringing is noted on the cross profile of the guider, the binning should be increased. Bin1 should only be used for the brightest of targets.

The guiding binning is adjusted from the PEPSI LBT GUI. Adjusting the binning on one side will automatically increase the binning for the guiding on the other telescope (they are linked together).

Updates to binning are outlined in terminal window where the PEPSI interface was started. Users should watch there for any issues. If guiding is unable to resume after a pause when adjusting the binning then shifts in binning may fail.

Users cannot simultaneously preset and change binning. When changing binning, the guiding is paused, changed, and then resumed.
