Analysing the flux stability of stellar calibrator candidates with TESS

Open Access

Fig. 8

Variability fractions of the stars in the calibrator candidate sample as a function of magnitude. Following Ciardi et al. (2011), the blue curve represents the fractions of stars with $χ_{v}^{2} > 2$ $\chi_{v}^{2}>2$ , the green curve the fractions of stars with $χ_{v}^{2} > 10$ $\chi_{v}^{2}>10$ , and the orange curve the fractions of stars with $χ_{v}^{2} > 100$ $\chi_{v}^{2}>100$ .
