FIESTool itself was modified to improved the configuration-file management in order to allow for easy automation of the pre-reduction of calibration data for the online pipe-line. It is planned to further improve the program to enable automation of the pre-reduction of calibration images such that an online quick-look reduction can be offered in an easy way. It is also planned to improve FIESTool regarding the wavelength solution, allowing for new ThAr frames to be used automatically. There should also be way to use the ThAr frame obtained closest in time to the target spectrum.
