Das Lumineszenzpaket

Das Paket 'Luminescence' beinhaltet eine Reihe von Funktionen, um Messdaten zu analysieren und graphisch darzustellen. Um den Anforderungen bei der Auswertung gerecht zu werden, wird es kontinuierlich weiter entwickelt. Aus diesem Grund sind nicht immer alle bis dato erstellten Funktionen hier aufgeführt. Einen aktuellen und ausführlicheren Überblick finden Sie im Luminescence-Manual.

In der unteren Tabelle sind die Funktionen alphabetisch aufgelistet.
