Photographic plates were digitized using professional flatbed scanners of type EPSON Expression 10000XL and were processed to the present digital form. The plate digitization projects (D.Groote) was funded by DFG grant GR969/4-1 and SCM1032/552. Investigators using these scans are kindly requested to include the following acknowledgements in any publications. The material in these archives can be used for scientific purposes free of charge.
