VizieR Online Data Catalog: Giant stars in TESS continuous viewing zones (Mackereth+, 2021)

We compile a target list of stars in and near to the TESS southern continuous viewing zone (SCVZ), by making a cone-search from Gaia DR2 (Gaia Collaboration 2018A&A...616A...1G, Cat. I/345) within 20° of the southern ecliptic pole. We cross-match this set with 2MASS (Skrutskie et al. 2006AJ....131.1163S, Cat. VII/233) and select stars with G<11 and parallax signal-to-noise >20. We then select stars with (J-K_S)>0.5 and M_H<3 (estimating M_H using only the inverted parallax and ignoring the effects of extinction - although we do account for this later), isolating a final sample of 15405 giant stars.

We extract photometry from the TESS FFIs for all 15405 stars in the target list, following the methods presented in Nardiello et al. (2019MNRAS.490.3806N, Cat. J/MNRAS/490/3806).

The power spectra are analysed by three pipelines to determine the global parameters ν_max, the frequency at maximum power, and Δν, the mean spacing between pressure modes of the same degree l at successive radial orders. The pipelines in question are presented in Mosser & Appourchaux (2009A&A...508..877M), Elsworth et al. (2020RNAAS...4..177E), and Mathur et al. (2010A&A...511A..46M); we refer to them here as COR, BHM, and A2Z, respectively (similarly to, e.g. Pinsonneault et al. 2018ApJS..239...32P, Cat. J/ApJS/239/32).
