3.2 Properties of the input data

Author(s): Uli Bastian

This section describes the input data from which the astrometric and photometric pre-processing – and thus the DPAC data processing as a whole – starts. The input data largely fall into two categories: telemetry data from the Gaia satellite, and auxiliary data prepared by the DPAC in advance of the mission or generated by DPAC in previous data reduction cycles.
