2.1.6 lens_observation

This table contains the observations associated with the components found in the lens candidates table.

Columns description:

solution_id : Solution Identifier (long)

All Gaia data processed by the Data Processing and Analysis Consortium comes tagged with a solution identifier. This is a numeric field attached to each table row that can be used to unequivocally identify the version of all the subsystems that were used in the generation of the data as well as the input data used. It is mainly for internal DPAC use but is included in the published data releases to enable end users to examine the provenance of processed data products. To decode a given solution ID visit https://gaia.esac.esa.int/decoder/solnDecoder.jsp

source_id : Unique source identifier (long)

A unique single numerical identifier of the source obtained from the Gaia DR3 main source catalogue (for a detailed description see gaiadr3.gaia_source.source_id).

component_id : Index of the component for this source_id (int)

An index used to identify the various components found around this source_id. This number varies between 1 and lens_candidates.n_components.

observation_id : Counter for the observations of each component (int)

A sequential counter that uniquely identifies the observations belonging to a given component.

ra_obs : Right ascension of each individual observation belonging to this component, as decoded from the transit_id (double, Angle[deg])

Right ascension of each individual observation belonging to this component, as decoded from the transit_id.

dec_obs : Declination of each individual observation belonging to this component, as decoded from the transit_id (double, Angle[deg])

Declination of each individual observation belonging to this component, as decoded from the transit_id.

g_flux_obs : Flux value of each individual observation belonging to this component (double, Flux[e${}^{-}$ s${}^{-1}$])

Flux value of each individual observation belonging to this component. Note that this value may be missing in some cases.

g_flux_obs_error : Flux error value of each individual observation belonging to this component (float, Flux[e${}^{-}$ s${}^{-1}$])

Flux error value of each individual observation belonging to this component. Note that this value may be missing in some cases.

g_mag_obs : Onboard G magnitudes of each individual observation belonging to this component (float, Magnitude[mag])

Onboard G-band magnitude of each individual observation belonging to this component.

epoch_obs : Epoch of the individual observation belonging to this component (double, Time[Barycentric JD in TCB $-$ 2 455 197.5 (day)])

Epoch of the individual observation belonging to this component, given as Julian Days in TCB at the Barycentre, minus 2 455 197.5 days.
