Description

Appendix plots for the paper: "The Kinematics of 30 Milky Way Globular Clusters and the Multiple Stellar Populations within"

Here we show the combined rotation analysis for the dynamically youngest (age/relaxation time <  4.5) clusters in our sample, as well as notable clusters such as NGC 2808 and NGC 7078. The left panel shows the position angle in the plane of the sky for all stars (green), P1 stars (blue) and P2 stars (red), with the values shown as circles and the errorbars shown as lines. In grey is the photometric semi-major axis as calculated in Section 3.1, with the errors represented as the width of the line.
The middle panel shows the calculated inclination angle of all stars (green), P1 stars (blue) and P2 stars (red), with the width of the lines corresponding to the error in the inclination angle and the extent of the line corresponding to the total rotational amplitude of the cluster, as shown on the x-axis.\\
Finally, the right panel shows the probability distributions of the total rotational amplitudes for all stars (green), P1 stars (blue) and P2 stars (red), with the corresponding median values and uncertainties displayed in the legend. In this way, we are able to visually identify the rotational differences between the different samples.
