Age bracketing of the Meingast 1 stream with empirical isochrones, whose corresponding cluster CMDs are shown in the right column of the figure. The gray points indicate the combined data of all three clusters, and the population connected to the plotted isochrone is overlaid in blue. By comparing the empirical isochrone of the stellar stream (yellow line) with similar archive isochrones, we bracketed the stream and, in extension, its relative age, by the Pleiades (magenta line) and by the Blanco 1 cluster (green line).
