2mass/Hipparcos Extinctions and Distances in the Serpens - Aquila Region.IV. Error Propagation. Individual stars and mean values

Jens Knude

We estimate errors from the application of the main sequence $(H-K{)}_{0}vs.(J-H{)}_0$ and $(J-K{)}_{0}vs.M_J$ relations on 2mass photometry to provide stellar extinctions and di…
