source: branches/FACT++_scripts_refactoring/Observation_class.js@ 18234

Last change on this file since 18234 was 18172, checked in by dneise, 9 years ago
Also this file has been changed by Daniela Dorner in February, while introducing the new CUSTOM run feature. It has been tested now since quite a while, so I take the liberty to check it in.
