Open cluster CMDs
Aggregazione dei criteri
In class, we found a way to isolate an open cluster within GAIA observational data; replicate this exercise for another cluster. Using the brightest stars, determine the mean parallax and proper motion (in RA and Dec) of the OC.
Present the completed work in a short report, which should also include a CMD showing the sequence of the chosen OC, comparing it to the one analyzed in class using the absolute magnitudes of both clusters (highlighting potential differences in the turn-off and population of the two OCs).
