Cross-matches between Gaia EDR3 sources on the one hand and Hipparcos-2, Tycho-2 + TDSC merged, 2MASS PSC (merged with 2MASX), SDSS DR13, Pan-STARRS1 DR1, SkyMapper DR1, GSC 2.3, APASS DR9, RAVE DR5, allWISE, and URAT-1 data on the other hand.About 1.5 million celestial reference frame (Gaia-CRF) sources.

Full passband definitions for G, G BP, and G RP.

Please be aware that the photometric system for the G, G BP, and G RP bands in Gaia EDR3 is different from the photometric system as used in Gaia DR2 and Gaia DR1.

G BP and G RP magnitudes for around 1.5 billion sources.

G magnitudes for around 1.8 billion sources.

In addition, two-parameters solutions – positions on the sky (α, δ) – for around 300 million additional sources.

The astrometric solution wil be accompanied with some new quality indicators, like RUWE, and source image descriptors.

The five-parameter astrometric solution – positions on the sky (α, δ), parallaxes, and proper motions – for around 1.5 billion (1.5 10 9) sources, with a limiting magnitude of about G ≈ 21 and a bright limit of about G ≈ 3.

An overview page for Gaia Early Data Release 3 helps to find all relevant information for the Gaia EDR3 release. A description of the expected contents of Gaia Early DR3 is given below.

The full Gaia Data Release 3 (Gaia DR3) is planned for the first half of 2022.Īs for previous releases, the Gaia (E)DR3 data will be made available through the Gaia Archive and partner data centres. Gaia EDR3 is planned to be released on 3 December 2020 at 12:00 CET. Gaia Data Release 3 is split into two releases: the early release called Gaia Early Data Release 3 (Gaia EDR3) and the full Gaia Data Release 3 (Gaia DR3). The complete schedule of next publication of Gaia data can be found here. Due to the availability of fuel and good performance, the mission was extended to 31 December 2022, subject to a mid-term review in 2020. Its nominal mission ended after 5 years of successful operation on July 2019. Use a snapshot more recent than skychart-3.7-2252 to build an index more than 2GB in size.Gaia was launched on 19 December 2013 at 09:12 UTC. If you use Linux or Mac OS, be sure to read the specific notes in the Catgen documentation page. You can start by loading the project file used for the standard catalog. Then use Catgen to convert the text files to a binary catalog optimized for chart display. The -cddir option must point to the folder containing u4b/, not the individual data files. Run the program in a console to show the syntax help.

You can download u4conv for Windows and Linux or get the source code. It also remove the streak by using the file streaklist.txt. The advantage of u4conv is it process all the files at a time, add the star identifier, a selected magnitude and the color index after the other data. Then convert the binary data on the DVD to ASCII text files using the include u4dump program or my u4conv program. See USNO UCAC page for more information and to get the script required to correct the binary data.

You must first copy the DVD content to your disk to correct for the error with the high proper motion stars. This allow you to include more or less information for each star depending on your needs. If you have a copy of the UCAC4 DVD, or if you download the full u4b folder from the CDS or a web mirror, you can use Catgen to build your own catalog from the original data files.
