Description
Supplementary material to the work "Calibration of the H\(\alpha\) Age-Activity relation for M dwarfs". We include the following two samples: We compiled 89,270 M dwarfs with H\(\alpha\) equivalent widths (H\(\alpha\)EW) measurements from the literature. From this sample we were able to age-date 892 M dwarfs (1,121 including repeated stars which represent extra measurements of H\(\alpha\)EW). These ages were obtained by identifying M dwarfs which belong to known young associations, or are co-moving with a white dwarf of known age. To identify co-movers we used kinematics and parallaxes from Gaia DR2.
