LHS 1140 EFE SED, calculated with data from the CDS. The points are listed in Table 2. Red points mark the black-body temperature estimation. Gray symbols are 2MASS data. UVOT UVW2 NUV flux is represented by the blue triangle. FUVG flux estimated with FUVG −NUVG correlation is represented by the orange triangle. The black arrow shows the 3σ upper limit to the X-ray flux of LHS 1140 at 1 keV. The blue line is the black body model with a temperature of 3015 K.
