VizieR Online Data Catalog: V348 And and V572 Per: heliocentric minima and RVs (Zasche+, 2019)
Abstract
All of our new spectroscopic observations were secured in the Ondrejov observatory in Czech Republic, using the 2 m telescope. The classical slit spectrograph has a resolution of R~12500. The individual exposure times were chosen according to the quality of the particular night, typically 800-3600 s. All of the spectrograms were reduced in a standard way, the wavelength calibration was made via a ThAr comparison spectra obtained before and after the stellar ones. The flat fields were taken in the beginning and end of the night and their averages were then used for the reduction. After that, the radial velocities (RV) were derived with the program SPEFO (Horn et al. 1996, J/A+A/309/521, or Skoda 1996ASPC..101..187S), on several absorption lines in the measured spectral region around Hα (usually Fe, Ca, or Si lines), with using the zero-point correction via measuring the telluric lines. Owing to the relatively high brightness of these stars, only rather small telescopes were used for the photometric observations. The system V348 And was observed (by P. Svoboda) with only the 34 mm refractor at his private observatory in Brno, Czech Republic, using the SBIG ST-7 CCD camera. The second star V572 Per was monitored with the similar instrument at the private observatory (by R. Uhlar) in Jilove u Prahy, Czech Republic, using a G2-0402 CCD camera. All of the measurements were reduced in a standard way using the program C-MUNIPACK, which is based on aperture photometry and uses the standard DAOPHOT procedures (Tody 1993ASPC...52..173T). The photometric data were obtained during the time span of 2007-2018. Nevertheless, some of the older data were only used for the minima times derivation. All of these data were secured in the Johnson-Cousins photometric system (Bessell 1990PASP..102.1181B), particularly the system V348 And was observed in BVR, while the system V572 Per in BVRI filters.
