TL;DR: In this article, the authors describe the calibration model of the Gaia photometric passband for Gaia Data Release 1, focussing on the G band photometry, and describe the photometric calibration pipeline explained here was applied to the first data release with good results.

TL;DR: In this paper, two ground-based observing campaigns aimed at building a grid of approximately 200 spectrophotometric standard stars (SPSS), with an internal ≃ 1 per cent precision and tied to Vega within ≃ 3 per cent, for the absolute flux calibration of data gathered by Gaia, the European Space Agency (ESA) astrometric mission.

TL;DR: In this paper, the authors quantitatively evaluate instrumental effects that might have a significant (i.e.,$\geq$1%) impact on the Gaia SPSS flux calibration.

TL;DR: In this article, the authors quantitatively evaluate instrumental effects that might have a significant (i.e., ≥ 1 %) impact on the Gaia SpectroPhotometric Standard Stars (SPSS) flux calibration.

TL;DR: In this article, two ground-based observing campaigns aimed at building a grid of approximately 200 spectrophotometric standard stars (SPSS), with an internal ~1% precision and tied to Vega within 3%, for the absolute flux calibration of data gathered by Gaia, the ESA astrometric mission.
