Goal here is to establish if we can find older clusters that span the full width of the main sequence in the Davenport plot. This is important because we can't calibrate/check how the rotation periods vary with space in the CMD if we don't have stars at those location in the CMD! (and this is related to issue #6)
We can wait to add other clusters until M67 is done, but Figure 1 of this paper on NGC 6811 gives a very good example of how this selection is done: https://arxiv.org/abs/1905.06869

First cluster to start with is M67: see the central coordinates and recommendations for Gaia selection in the first few paragraphs off this paper: https://ui.adsabs.harvard.edu/abs/2019arXiv190502020C/abstract (and potentially references therein)
