Wer von dem obigen oder nachfolgenden Material Gebrauch machen möchte, sollte aus urheberrechtlichen oder wissenschaftlichen Gründen wie folgt zitieren: Dr. Lukas Schuler, Dark-Sky Switzerland, «In welchem Licht strahlt der Vollmond?» ORION 401 (2017), S. 14-18, ISSN0030-557 X
Im obigen Artikel wurde versprochen, dass die spektralen Daten von Sonne und Mond nach dem Erscheinen auf dieser Seite online zur Verfügung gestellt werden.
Das sei hiermit getan:
Spektrum der Sonne aus Abbildung 4 vom 27. Mai 2017 16:35 Uhr MESZ, Einzelmessung korrigiert für Remission auf Papier, Details siehe obigen Artikel.
Durchschnittliches, für die Transmission des Objektivs korrigiertes Spektrum des Vollmondes vom 11. Mai 2017 um 02h:33.5m ± 8.4 min MESZ, Details siehe Artikel, Abbildung 7 und Tabelle 3.
