5.2 ext_phot_zero_point

Definition of the Gaia photometric system: for GDR1 only zero-points will be computed, one for G and one for each integrated BP and integrated RP. The adopted photometric system will be Vega.

Columns description:

solution_id : Solution Identifier (long)

The data in the MDB will be described by means of a ”Solution identifier” parameter. This will be a numeric field attached to each table row that can be used to unequivocally identify the version of all the subsystems that where used in the generation of the data as well as the input data used. Each DPC generating the data will have the freedom to choose the Solution identifier number, but they must ensure that given the Solution identifier they can provide detailed information about the ”conditions” used to generate the data: versions of the software, version of the data used…

g_mag_zero_point : G magnitude zero point (double, Magnitude[mag])

The magnitude zero point on the Vega scale for the G passband.

g_mag_zero_point_error : Error on the G magnitude zero point (double, Magnitude[mag])

bp_mag_zero_point : BP magnitude zero point (double, Magnitude[mag])

The magnitude zero point on the Vega scale for the BP passband.

bp_mag_zero_point_error : Error on the BP magnitude zero point (double, Magnitude[mag])
