Determine the distance to the Pleiades. 1. Overlay the two graphs from part A so that the B-V axes align exactly AND so that the main sequences in each graph overlay each other as well. 2. Calculate the offset between the vertical axes of the overlapped graphs by taking the difference between a V value from graph 1 and the corresponding My value from graph 2
