SUMER study: Filament raster in He I 584 and O I 1152

Remarks: The study was initiated by T. Kucera (NASA/GSFC). Her comment: "The filament 'blew' before we could observe it. ... I'll be running the same program over again a few times in the next week or so. - The purpose of the study is to measure flows in filaments. The raster is just supposed to be for context."
