Table E.3.
Stars for which we calculated the emission measure-weighted coronal temperatures kTwgt. Because only the ratio between EM of each component matters for calculating kTwgt, they are listed as unitless in the table.

Notes. *EM is not listed in the paper. EM1 = EM2 = 0.5 is thus assumed for calculation.
