VizieR Online Data Catalog: Spectroscopic results on ROSAT late-type stars (Zickgraf+, 2005)

Paper III (Appenzeller et al., 1998, Cat. <J/ApJS/117/319>) presents a catalogue of optical identifications for 685 RASS sources contained in six study areas. The catalogue contains 254 X-ray sources which have been identified as coronal emitters of spectral types F to M.

The stellar sample of G to M above was observed spectroscopically during several observing runs. Low-resolution spectra were obtained with CAFOS, high-resolution spectra were observed with FOCES, both attached to the 2.2m telescope at Calar Alto observatory (CA), Spain. Further high- and medium-resolution observations were obtained at the Observatoire de Haute Provence (OHP), France, with the spectrographs AURELIE and CARELEC at the 1.52m and 1.93m telescopes, respectively. A few supplementary high- and low-resolution observations were obtained at European Southern Observatory, La Silla, Chile (ESO), with CASPEC at the ESO 3.6m telescope and DFOSC at the Danish 1.54m telescope, respectively. A further observing run of 5 nights at Calar Alto observatory in February 2001 was lost due to bad weather conditions.
