VizieR Online Data Catalog: Low-mass stars from the first two TESS sectors (Cloutier, 2019)

Our initial stellar sample is retrieved from version 7 of the TESS Input Catalog (TIC-7), which is accessed via the Barbara A. Mikulski Archive for Space Telescope (MAST) Portal (http://mast.stsci.edu/portal/Mashup/Clients/Mast/Portal.html). To identify putative low-mass dwarf stars within the TIC-7, we first restrict our sample to sources flagged as dwarf stars based on their 2MASS colors and the reduced proper motion criterion from Stassun et al. (2018, J/AJ/156/102), modified from Collier Cameron et al. (2007MNRAS.380.1230C). We further restrict our sample to stars whose "priority" is >=10^-3, where the TIC priority metric is based on the relative probability of detecting small planetary transits. As such, the priority is dependent on R_s, the expected photometric precision, the number of TESS sectors in which the TIC member will be visible, and its contamination ratio, which is the ratio of contamination to source flux where contamination is computed over 10 TESS pixels from the source (~3.5 arcmin). Our final stellar sample contains 1599 low-mass stars with 537, 694, and 368 observed within TESS sectors 1, 2, and both, respectively. Photometric measurements and fundamental stellar parameters for our final stellar sample are reported in Tables 1 and 2, respectively.
