Quality control

As note above. There is an issue with the radial velocity stability of FIES when using the medium-resolution fiber, though with the high-resolution fiber the results seem to be reasonable. A general problem is that we still do not have any plan or system to test and analyze the stability of the system (using any of the fibers).

A test and analysis program will be defined and implemented. For the data reduction it was agreed with Lars Buchave that we can use his programs to reduce the data.

A quality control script will be made that checks for changes in ThAr line-ratios in order to detect the ``dying-lamp'' phenomenon. A database will be made of the results to monitor the calibration lamps.
