We provide the radial velocities of 55000 stars for the globular cluster NGC 3201 as they were published in Giesers et al. 2019. We also provide the resulting binary properties table (Table A2) here. We kindly ask you to cite this paper when using the data.

All this data is also available at CDS: http://cdsarc.u-strasbg.fr/viz-bin/cat/J/A+A/632/A3

Data

The data of the radial velocity sample is divided into three subsets: the radial velocities of the cluster member stars (tableA1_member.csv), the radial velocities of the foreground stars (tableA1_nonmember.csv), and the radial velocities of RR Lyrae-type and SX Phoenicis-type stars (tableA1_RRLyr_SXP).

The files starting with tableA1 contain the following columns:

  • ACS_Id - The identifier in the HST/ACS catalogue (Sarajedini+, 2007)
  • RA - Position taken from the ACS catalogue
  • Dec - Position taken from the ACS catalogue
  • Magnitude - Magnitude (F606W) taken from the ACS catalogue
  • Date - The observation date of the measurement (in days)
  • Vrad - The barycentric radial velocity (in km/s)
  • Vrad_err - The uncertainty of the radial velocity (in km/s)
  • P_var - The probability of the star to be variable in radial velocity

The tableA2.csv contains the following columns:

  • ACS_Id - The identifier in the HST/ACS catalogue
  • RA - Position taken from the ACS catalogue
  • Dec - Position taken from the ACS catalogue
  • Period - period of likely Keplerian solution (in days)
  • Period_err - uncertainty of period (in days)
  • Eccentricity - eccentricity of likely Keplerian solution
  • Eccentricity_err - uncertainty of eccentricity
  • Amplitude - amplitude of likely Keplerian solution (in km/s)
  • Amplitude_err - uncertainty of amplitude (in km/s)
  • Vis_mass - mass of the measured visible binary component (in solar mass)
  • Vis_mass_err - uncertainty of the visible mass (in solar mass)
  • Invis_mass - derived minimum mass (M sin i) of the invisible binary companion (in solar mass)
  • Invis_mass_err - uncertainty of the invisible mass (in solar mass)
  • Comment - comment providing more information
