Notes. Column 1 is the OB star identity in the catalog of Reed (2003); Column 2 is the unique source identifier in Gaia DR2. Columns 3 and 4 are barycentric right ascension (RA) and declination (Dec). Columns 5–7 give the parallax and proper motion in the eastward (μx = μα cos δ) and northward directions (μy = μδ). Column 8 lists local standard of rest (LSR) velocity converted from the heliocentric value. Column 9 is the spectral type of the stars. In Gaia DR2, the reference epoch is J2015.5. The full table is available at the CDS.
