Information on resource 'A Gaia DR2 mock stellar catalog'

Services defined within this resource descriptor

• Gaia DR2 Mock Bulk Download

  A facility to download the raw FITS tables containing the generated data for the Gaia DR2 mock tables. Almost all users will want to use the ingested and processed table gdr2mock.main on the TAP service at http://dc.g-vo.org/tap instead.

  Rough metadata for the FITS binary tables is available from gdr2mock.generated_data. To download the files, visit gdr2mock/q/download/static.

Tables defined within this resource descriptor

• gdr2mock.astrometric_performance2

  This table gives numerical factors to be applied to the sky-averaged astrometric errors for the different astrometric parameters as function of ecliptic latitude β, including the effect of the variation of the number of transits over the sky. Source: https://www.cosmos.esa.int/web/gaia/table-2

• gdr2mock.astrometric_performance6

  This table gives numerical factors to be applied to the sky-averaged astrometric errors for the different astrometric parameters as function of ecliptic latitude β, including the effect of the variation of the number of transits over the sky. Source: https://www.cosmos.esa.int/web/gaia/table-6

• gdr2mock.generated_data

  This contains the data actually generated. Users probably want to use the gdr2mock.main table that (fairly well) follows the Gaia DR2 data model.

• gdr2mock.main – queryable through TAP and ADQL

  A synthetic Milky Way catalog mimicking GDR2 in stellar content and data model.

• gdr2mock.photometry – queryable through TAP and ADQL

  This table contains simulated absolute magnitudes to about 0.1 mag precision for all the stars, as well as extinctions in several bands; To use it, join it USING (parsec_index) with the gdr2mock.main table.

• gdr2mock.raw_exts

  Extinctions for Gaia DR2 mock photometry. This is joined into the parsec_phot view.

• gdr2mock.raw_phot

  Absolute magnitude for Gaia DR2 mock in various photometric bands. This is joined with the raw_extinctions to give the gdr2mock.photometry.
