De eerste Gaia data release, Gaia DR1, omvat astrometrie en photometrie van meer dan 1 miljard bronnen helderder dan magnitude 20.7 in het witte-licht photometrische band G van Gaia. Het Gaia Data Processing and Analysis Consortium (DPAC) bewerkte de ruwe metingen die gedurende de eerste 14 maanden van de missie met het Gaia instrumentarium zijn verzameld en maakten hiervan een astrometrische en photometrische catalogus.

Lees meer details over GAIA DR1 in de release documentatie.

DR1 een voorlopige release van de GAIA data. Er zijn delen van de hemel die nog ontbreken in de catalogus.
Gebruik deze gegevens niet wanneer een volledige weergave van de hemel belangrijk voor je is.

De zelfde beperkingen met dezelfde gaten zijn van toepassing op andere catalogi gebaseerd op GAIA DR1, zoals UCAC5 of HSOY.

You can immediately use the GAIA DR1 data with Skychart by using the VO catalog feature.

Make a chart with a FOV of less than one degree in the area of interest.
Open the Catalog settings.

Click Add in the VO catalog tab and search for GAIA, select the catalog I/337, click Select catalog.

Select the first tab I/337/gaia, enter the default magnitude: 20, click Download catalog.

Make sure the GAIA row is green and click the OK button.
You can return to the screen later to load the data for a new area with a click on the arrow in the Reload column.
Beware that the one degree FOV around M13 take 28 MB of data to download, so do not do it on large area.

You can also download this catalog for local offline use.
The easiest way is to download the catalog I prepare using Bittorent but you have the option to process the original data yourself.
The ready to use catalog include the fields: source_id, ra, dec, phot_g_mean_mag, no search index.

You can download this catalog using Bittorent, download size is 19 GB:

• Get the torrent file
• Open the torrent file in your bittorrent client software. You can eventually select only the zone directory you want. Always get the header file gaia.hdr.zip.
• Unzip every file to the same directory but keep the directory structure. Then open the file gaia.hdr from the Skychart menu Setup/Catalog/Catalog “Add” button.
• Please keep seeding to help other to get the data!

To build the catalog yourself using Catgen process as follow:

• Download my files I use to build the above catalog and use them as example.
• The file download.txt contain the download URL and a ready to use wget command.
• The file gaia_extract.sh is a shell script to format the csv data for use with Catgen. You can edit the script if you want to include other data field but be conscious this first release do not include more than the position and magnitude for 99.99% of the stars. On Windows you can run this script from the Cygwin shell.
• From Catgen open the example gaia.prj file and make the change you want before to run.
