Notes. The columns are as follows: (1) Dwarf ID; (2) Right ascension (J2000); (3) Declination (J2000); (4) Heliocentric velocity; (5) HI distance from Hubble flow; (6) W50 line width; (7) HI flux; (8) Signal-to-noise ratio; (9) log10 of the HI mass; (10) g-band absolute magnitude; (11) B-band absolute magnitude; (12) Galactic extinction corrected g − r color; (13) log10 of the stellar mass; (14) HI-mass-to-light ratio; (15) log10 of the dynamical mass; (16) Survey; (17) Morphology. Based on Poulain et al. (2021) for the dEs, dIs, and nucleated (indicated with “,N”), and on Marleau et al. (2021) for the UDGs. ATLAS3D* means that the dwarf has also been detected in the ALFALFA survey. This table is available in its entirety at the CDS.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
