TL;DR: In this article, the Hipparcos results on distances to nearby OB associations and open clusters are discussed and the shortcomings and assumptions in the analyses used to derive these results are pointed out and compared with results obtained from main sequence fitting.
Abstract: In the context of the luminosity calibration of the nearer stars I discuss the Hipparcos results on distances to nearby OB associations and open clusters. The shortcomings and assumptions in the analyses used to derive these results are pointed out and for the open clusters a comparison is made with results obtained from main sequence fitting. I conclude that given the considerable uncertainties in the latter technique there is no convincing evidence that the Hipparcos based distances to open clusters beyond the Hyades should not be trusted.
