M3
Our work consists in the analysis of the photometric study of the globular cluster M3.
Starting from the GAIA PORTAL DR3 (2022) 1 data, we created the H-R diagram and reproduced the diagram with the isochrone in order to measure the age of the cluster. We used Topcat to work on the graphics and CMD 3.6 2 input form to extract the isochrone. The main sequence corresponds to the isochrone aged 10 billion years, which is our estimated age for the cluster, subsequently confirmed by the comparison with the values in literature.
