Notes. The TIMED/SEE solar observations are detailed further in Sect. 3.1; Swift/XRT fluxes for HD 189733 are from Lecavelier des Etangs et al. (2012); the EUVE data used to constrain the flaring coronal model of AU Mic were taken in July 1992 (Cully et al. 1993). The solar values are used for HD 209458.
