GaiaHub is a public Python/Fortran tool that computes stellar proper motions combining data from the Gaia mission and the Hubble Space Telescope. The code helps users to discover, download, and analyze HST images in a sky region of interest, combining the results with the Gaia catalog to produce accurate proper motions. If you use GaiaHub for your research, please cite del Pino et al. 2022, where the method is described.

== Notes on Version 1.2.0 ==

  • Improved "--rewind_stars" option which iterates on the transformation fitting using Gaia-only (in the first iteration) and Gaia-HST (in subsequent iterations) PMs to provide better solutions.
  • Implemented "--load_existing" option which saves time by skipping the image checking procedure when the images have been previously downloaded.
  • Fixed bug: Gaia's positional uncertainties have been increased by default (Fabricius et al. 2021).
