VizieR Online Data Catalog: HAZMAT. III. Low-mass stars GALEX photometry (Schneider+, 2018)

In this third installment of the Habitable Zones and M dwarf Activity across Time (HAZMAT) series, we extend the study of the UV environments of low-mass stars at various ages to later spectral types. We investigated young associations and clusters from Shkolnik & Barman (2014, J/AJ/148/64) with confirmed low-mass members. These included the TW Hya Association (10+/-3 Myr; Bell et al. 2015, J/MNRAS/454/593), the β Pictoris moving group (24+/-3 Myr; Bell et al. 2015, J/MNRAS/454/593, 26+/-3 Myr; Nielsen et al. 2016AJ....152..175N, 22+/-6 Myr; Shkolnik et al. 2017AJ....154...69S), the Tucana-Horologium moving group (45+/-4 Myr; Bell et al. 2015, J/MNRAS/454/593), the AB Doradus Moving Group (149_-19⁺⁵¹; Bell et al. 2015, J/MNRAS/454/593), the Hyades (625+/-50 Myr; Perryman et al. 1998, J/A+A/331/81), and objects with field ages (~5 Gyr). All photometry gathered from GALEX for this paper was found using the GalexView tool (http://galex.stsci.edu/galexview/). We used a 10.0" search radius and proper-motion-corrected coordinates (to epoch 2007) for each object. We exclude all photometry with photometric flags that signal a bright star window reflection, dichroic reflection, detector run proximity, or bright star ghost, as recommended in the GALEX documentation.
