Detector

It is possible to readout the CCD using both amplifiers, which would cut the readout time nearly in half. This is of interest when using short exposures times. The only problem is that in the current set-up using this mode results in losing one column in the middle of the spectrum which basically removes a whole order from the resulting spectrum. It is in principle clear what the problem is, but the solution requires some work.
