VizieR Online Data Catalog: Photometry and RVs of BL Her stars (Wielgorski+, 2024)

Optical photometry in the Johnson B and V passbands were obtained with the VYSOS16 0.4-metre telescope located at Rolf Chini Cerro Murphy Observatory (Ramolla et al. 2013) with a pixel scale of 0.77arcsec/pix and a 41.2'x25.5' field of view.

Radial velocities were measured from spectra collected between 2016 and 2023 within dedicated programmes with four high resolution (40000-100000) spectrographs hosted by the European Southern Observatory (ESO). We used CORALIE, installed on the 1.2m 'Swiss' Leonhard Euler telescope at La Silla Observatory (Queloz et al. 2000); HARPS, installed on the 3.6m telescope at La Silla Observatory (Pepe et al. 2000); FEROS, installed on the 2.2m MPG/ESO telescope at La Silla Observatory (Kaufer & Pasquini 1998); and UVES, installed on the 8.2m VLT UT2 (Kueyen) telescope at the Paranal Observatory (D'Odorico et al. 2000, SPIE Conf. Ser., 4005, 121, filler programme).
