The characterisation of the High Throughput Imaging Echelle Spectrograph and investigations of hydrogen Balmer B emission over Svalbard
This thesis details the calibration of the High Throughput Imaging Echelle Spectrograph and observations of hydrogen Balmer β emission made with it from Svalbard. It presents calibration tools and instrumental artifact removal techniques. It introduces innovative techniques for removing sunlight and...
