Xitong Yue,Yuanyuan Shi,Huajian Caict that the 2A and 3G PSs perform significantly better than the 1F (presently adopted as a baseline PS for GAIA), we conclude that still there is no photometric system proposed to date, which would allow to achieve the scientific objectives of the GAIA mission.

GAIA: An Astrometric and Photometric Survey of our Galaxy of 2010–12. GAIA will provide positional, radial velocity, and photometric measurements with the accuracies needed to produce a stereoscopic and kinematic census of about one billion stars throughout our Galaxy (and into the Local Group), amounting to about 1 per cent of the Galactic stellar popula

Determination of Stellar Parameters with GAIAother planned survey will provide so much photometric information on so many stars. I examine the problem of how to determine fundamental physical parameters (.., log ., etc.) from these data. Given the size, multidimensionality and diversity of this dataset, this is a challenging task beyond

GAIA Photometric System: Evaluation of Performancethe analysis of virtually any multicolour PS designed for the global investigation of the Galactic stellar populations. Performance of the 1F, 2A and 3G PSs is evaluated taking into account their ability to simultaneously determine the main stellar parameters, .., log ., and .., for a large va
