Compare coordinates between Gaia DR1 and DR2. The transmitted window is centred on the brighter part of the acquired window, so the brighter component has a better chance to be selected, even when processing the fainter transit. 3 billion in terms of parallax and proper motion, and adds new data about stellar colours, line-of-sight velocities, surface temperatures, variability, radii, luminosities, and more. This structure is hardly accessible for Gaia as most. and implemented in their 3D "Bayestar" dust map of three-quarters of the sky. Bódi1,2 and L. More specifically, The 2018 Gaia Sprint: Seattle Satellite Edition, hosted by the eScience and DIRAC Institutes at UW. Additionally, epoch photometry in the G-band was released in Gaia DR1 for a small number of variable sources in the South Ecliptic Pole which covers the LMC. 5 billion all-.

The set of 762 new asteroid models that we reconstructed from combined inversion of Lowell and Gaia DR2 photometry significantly increases the total number of asteroids with known spin state and shape. We then refine their membership iteratively using both astrometry and photometry. When applied to Gaia DR2, the result is a high-purity catalog of accreted. 1 may contain erroneous models, their fraction should not be higher than a few percent. Combining the spatial and kinematic data we calculate Gaia 1 has a circular orbit with a radius of about 12 kpc, but with a large out of plane motion: z max =1. OB associations also map out the spiral arms, Gaia will probably only be able to do that for local structures [31]. Isochrone fits to Gaia, 2MASS, and Pan-STARRS1 photometry indicate that Gaia 1 is an intermediate age (∼3 Gyr) stellar cluster. RAVE also provides spectrophotometric parallax data, as well as cross-identification of stars with a number of other datasets, including Gaia DR2. 5 million stars (I don't know how many of those have also at the same time the 6D astrometric parameters but I estimate more.
