Parallactic distances and proper motions of virtually all stars in the sigma Orionis cluster or: How I learned to get the most out of TOPCAT and love Gaia DR2
Jos\'e A. Caballero
TL;DR
This paper demonstrates how to effectively utilize Gaia DR2 data and TOPCAT software to accurately determine parallactic distances and proper motions for nearly all stars in the sigma Orionis cluster, enhancing cluster analysis.
Contribution
The paper introduces a comprehensive methodology combining Gaia DR2 data with TOPCAT to improve the measurement of stellar distances and motions in the sigma Orionis cluster.
Findings
High-precision parallactic distances for most cluster stars
Refined proper motion measurements revealing cluster dynamics
Enhanced data analysis techniques for Gaia DR2 datasets
