Table information for 'gedr3mock.maglim_7'

General

Table Description:

This table gives empirical magnitude limits for G and BP bands derived from Gaia DR2 with G < 20.7 mag for HEALPixels of 7 (scale roughly ~0.5 degrees). For each band we have 4 different variants:

1. no additional condition,
2. parallax available,
3. BP-RP available,
4. parallax and BP-RP available.

For BP mag limits we also require that BP is available. The magnitude limits are approximated by the mode of the magnitude distribution in a specific HEALpix. Since this mode estimator is prone to Poisson noise in low density areas we report the magnitude limits in two flavours:

1. directly the mode estimator
2. the same as the mode estimator,

except that in healpixel with a stellar density below 1e5 sources per square degree the limit is arbitrarily set to 20.7 mag. These magnitude limits were created using the gdr2_completeness package and users are encouraged to create custom-made magnitude limits with specific conditions, e.g. RVS sample with good parallaxes.

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: This catalogue is a simulation of the Gaia EDR3 stellar content using Galaxia (a tool to sample stars from a Besancon-like Milky Way model), 3d dust extinction maps and the latest PARSEC Isochrones. It is mimicking the Gaia DR2 data model and an apparent magnitude limit of G=20,7. Extinctions and photometry in different bands have also been included in a supplementary table as well as uncertainty estimates using scaled GDR2 errors. Additional magnitude limit per HEALpix maps are provided, based on the mode in the magnitude distribution of Gaia DR2 data.
