HR-diagram showing the criteria for our selection of targets. The red line shows our limits on M_V and (B − V), and targets in the lower non-shaded region were selected for analysis. The marker colour indicates the V-band magnitude for the stars, while the marker size indicates the number of sectors TESS will have observed a given star in Cycle 6 (up to and including Sector 83). The stars in the top left shaded box are not expected to show solar-like oscillations and here we have not indicated V nor the number of sectors. The stars in the top-right shaded region contain evolved stars that may well show solar-like oscillations – these will be the subject of a future study.
