Flash/Heros Heidelberg spectra 2012-04-03T13:30:00 100 Spectra from the Flash and Heros Echelle spectrographs developed at Landessternwarte Heidelberg and mounted at La Silla and various other observatories. The data mostly contains spectra of OB stars. Heros was the name of the instrument after Flash got a second channel in 1995. 10.21938/oUuqajnWmofP2w75.Acc8g If you use this data, please acknowledge: "This research made use of Flash/Heros data served through the GAVO data center".
