The first GAIA data release is now available and can be used with Skychart

M13 with GAIA DR1

The first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magnitude 20.7 in the white-light photometric band G of Gaia. The Gaia Data Processing and Analysis Consortium (DPAC) processed the raw measurements collected with the Gaia instruments during the first 14 months of the mission, and turned these into an astrometric and photometric catalogue.

You can read more detail about GAIA DR1 in the release documentation

Missing data

DR1 is a preliminary release of the GAIA data and some sky area are still incomplete.
Do not use this data if complete sky coverage is important for you.

The same limitation with the same “hole” apply to the other catalog based on GAIA DR1, like UCAC5 or HSOY.

Use with Skychart

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.

Use a local catalog

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:

To build the catalog yourself using Catgen process as follow:
