Using systemic proper motions inferred from Gaia data, we find that globular cluster orbital poles are not clustered in the VPOS direction, though the population with the highest VPOS membership fraction is the young halo clusters (~30%).

Due to the assumptions made in our gamma-ray data analysis, our bounds are comparable to previous bounds on both the $p$-wave and Sommerfeld-enhanced cross sections using dSphs.

From this compilation we test for scaling relations between the J and D-factors and physical properties of the dSphs such as the velocity dispersion ($\sigma_{\mathrm{los}}$), the distance ($d$), and the stellar half-light radius ($r_{1/2}$).
