Acknowledgments
MAST made extensive use of the TUES pages from the Institute for Astronomy and
Astrophysics Tübingen (IAAT) at the University of Tübingen
in Tübingen, Germany.
Special thanks go to Jürgen Barnstedt from the TUES project
for providing software, data, numerous documents and
answers to our almost infinite number of questions.
