2023-02-07 Updates to the Gaia Archive data tables and Gaia DR3 known issue "Variability: planetary transits"

Today, three tables have been added to the Gaia Data Release 3 catalogue in the Gaia Archive:

• A new table chemical_cartography was added derived from the paper "Gaia Data Release 3: Chemical cartography of the Milky Way"
• A new table vari_spurious_signals was added derived from the paper "Gaia Data Release 3: Gaia scan-angle dependent signals and spurious periods"
• The data in the table gaiadr3.vari_planetary_transit, originally published on 13 June 2022, contained serious errors and users were advised on 23 June 2022 not to use them (see this known issue). On 7 February 2023, the original, erroneous table was renamed to gaiadr3.vari_planetary_transit_13june2022 and replaced by a new table with the (original) name vari_planetary_transit

Following the updated table gaiadr3.vari_planetary_transit, the Gaia DR3 known issue "Variability: planetary transits" was updated as well reflecting the changes made to the name of the erroneous table. The information of this known issue is copied below:

The Gaia DR3 table named vari_planetary_transit contains information on the period and other properties (transit reference time, depth, duration, etc.) of 41 new planetary transit candidates and 173 known exoplanets (Eyer et al. 2022, Panahi et al. 2022). The data in the table gaiadr3.vari_planetary_transit, originally published on 13 June 2022 with solution_id = 375316653866487564, contained serious errors and users were advised on 23 June 2022 not to use them.

On 7 February 2023 at 11:00 CET, the original, erroneous table was renamed to gaiadr3.vari_planetary_transit_13june2022 and replaced by a new table with the (original) name gaiadr3.vari_planetary_transit and solution_id = 375523436409132247. This change applies to the table available from the Gaia ESA Archive as well as from the bulk-download repository.

Finally, these changes have been incorporated into the Gaia data release documentation along with updates to the executive summary and the references to some papers. A new version "Gaia data release 3 documentation version 1.2" has been released today as well.
