6. ADASS 2002 Conference Proceedings
... Previous: Desmearing Solar System Objects in Chandra Data . ... We review the data reduction of two fiber-based echelle spectrographs (HEROS and FEROS) with emphasis on the similarity of the inconsistencies between the overlap of spectral orders before merging. ... The data suggest a very similar shift of the blaze function over all orders in the case of FEROS, leading to larger overlap mismatch in the narrower orders in the blue spectral region i.e., with larger gradients in the blaze function. ...

13. OFO IKI / OSD
The Optical Solar Sensor (OSD) has been designed to determine the direction towards the center of the Sun's visible disc. The direction to the Sun is computed in the instrument coordinate system relative to the pixels' position on the linear CCDs illuminated with the light passed through the incoming coding mask. The OSD coding mask has three groups of slits with three slits in each group. This mask configuration provides for reliability increase as well as for the required accuracy. ...
