cds-question@unistra.frglobular-star-clustersproper-motionshst-photometryinfrared-photometryvisible-astronomyphotometryWe present an improved data-reduction technique to obtain high-precision proper motions (PMs) of globular clusters (GCs) using Hubble Space Telescope data. The new reduction is superior to the one presented in the first paper of this series for the faintest sources in very crowded fields. We choose the GC NGC 362 as a benchmark to test our new procedures. We measure PMs of 117450 sources in the field, showing that we are able to obtain a PM precision better than 10{mu}as/yr for bright stars. We make use of this new PM catalog of NGC 362 to study the cluster's internal kinematics. We investigate the velocity dispersion profiles of the multiple stellar populations hosted by NGC 362 and find new pieces of information on the kinematics of first- and second- generation stars. We analyze the level of energy equipartition of the cluster and find direct evidence for its post-core-collapsed state from kinematic arguments alone. We refine the dynamical mass of the blue stragglers (BSs) and study possible kinematic differences between BSs formed by collisions and mass transfer. We also measure no significant cluster rotation in the plane of the sky. Finally, we measure the absolute PM of NGC 362 and of the background stars belonging to the Small Magellanic Cloud, finding a good agreement with previous estimates in the literature. We make the PM catalog publicly available.2018ApJ...861...99Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/861/99CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/hst : HST Archived Exposures Catalog (STScI, 2007)I/337 : Gaia DR1 (Gaia Collaboration, 2016)VII/195 : Globular Clusters in the Milky Way (Harris, 1996)J/A+AS/93/293 : Astrometry of globular clusters (47 Tuc) (Tucholke 1992)J/AJ/106/1508 : Dynamics of globular cluster NGC 362 (Fischer+ 1993)J/AJ/109/218 : Catalogue of globular cluster profiles (Trager+ 1995)J/A+A/360/472 : Proper motions in omega Centauri (van Leeuwen+, 2000)J/AJ/122/2569 : VI photometry of NGC 288, 362 and 1851 (Bellazzini+, 2001)J/AJ/134/1298 : CaII EWs in 29 Galactic clusters (Carrera+, 2007)J/A+A/463/589 : Variables stars in NGC 362 (Szekely+, 2007)J/A+A/557/A138 : Detailed abundances in the GlC NGC 362 (Carretta+ 2013)J/ApJ/797/115 : HSTPROMO I.
