Notes. The number of these plates are given for both objective-prism plates and single spectra as well as the period of time in which they were observed. Abbreviations used: LA = Lippert-Astrograph; 1m = 1 m-spectroscope; SS = original Schmidt’sches Spiegelteleskop; KS = Kleiner Schmidtspiegel II; GS = Großer Schmidtspiegel (80 cm) at Hamburg Observatory, HS = same Schmidt telescope at Calar Alto; ES = ESO Schmidt telescope at ESO (La Silla).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
