We thank the Heidelberg-Tübingen team for their support and the data reduction at the instrumental level. We thank in particular H. Widmann for helpful discussions. ORFEUS could only be realized with the support of the German and American colleagues and collaborators. The ORFEUS project was supported by DARA grant WE3 OS 8501, WE2 QV 9304 and NASA grant NAG5-696. PR is supported by a grant from the DARA (now DLR) under code 50 QV 9701 3.
