VizieR Online Data Catalog: The Pristine survey. IX. (Venn+, 2020)

Targets were selected from the Pristine survey catalogue which includes 28557 bright (V<15) stars in the original ~1000sq.deg² footprint between 180<RA<256° and +00<Dec<+16° (Starkenburg et al. 2017MNRAS.471.2587S; Youakim et al. 2017MNRAS.472.2963Y, Cat. J/MNRAS/472/2963).

Pristine survey targets were cross-matched with the SDSS photometry to obtain ugri broad-band magnitudes used for colour temperature determinations and point-source identification. Additional selection criteria were adopted, as described by Youakim et al. (2017MNRAS.472.2963Y, Cat. J/MNRAS/472/2963Y). The SDSS gri-band photometry was further used for a colour selection, where 0.25<(g-i)₀<1.5 and 0.15<(g-r)₀<1.2 correspond to the temperature range 4200K<T_eff<6500K, covering the tip of the red giant branch and the cooler main sequence to the main-sequence turn-off.

The 115 stars observed at CFHT with the high-resolution (R~68000) ESPaDOnS spectrograph (Donati et al. 2006ASPC..358..362D) are listed in Table 1.

The kinematics and orbits for all 70 of the metal-poor candidates have been determined using the Gaia DR2 data, our RVs, and adopting the MWPotential14 in the Galpy package (with a slightly more massive halo).
