An astrometric and photometric study of the intermediate-age open cluster NGC 2158 and its eclipsing binary NBN201578

We present a photometric and astrometric analysis of the NGC 2158 cluster using Gaia DR2 and 2MASS data. The cluster age, color excess, intrinsic distance modulus and distance are calculated to be t = 2.240 ± 0.260Gyr, E(B − V ) =0.420±0.050mag, (m−M)⊙=12.540±0.130mag and d⊙=3224±200pc respectively....
