VizieR Online Data Catalog: GOSSS III. 142 additional O-type systems (Maiz Apellaniz+, 2016)

Most of the spectra presented in Paper I (see III/274) were obtained with the Albireo (Observatorio de Sierra Nevada-OSN-1.5m telescope) and TWIN (Calar Alto-CAHA-3.5m telescope) spectrographs. On the other hand, most of the spectra in Paper II (see III/274) were obtained with the Boller & Chivens spectrograph at the Las Campanas (LCO) 2.5m du Pont telescope. Starting with Paper II, some spectra were also obtained with the ISIS spectrograph at the 4.2m William Herschel Telescope (WHT) at the Observatorio del Roque de los Muchachos (ORM) in La Palma, Spain. In this paper, we use data from all of the above instruments and we also add a new one, OSIRIS, at the 10.4m Gran Telescopio Canarias (GTC) at the ORM. The GOSSS data in this paper were obtained between 2007 and 2015.
