CTI effects models for Gaia
It is probably hard to underestimate the effort required to coordinate the Gaia hardware and software development. While the actual satellite and onboard software has been developed by the industrial consortium EADS-Astrium, the scientific data processing is done by the Data Processing and Analysis Consortium (DPAC). As explained in an earlier blog entry, DPAC consists of several hundred people in dozens of scientific institutes spread all over Europe. Because the scientific requirements of the Gaia measurements are on the edge of what seems physically possible, every aspect of the hardware must be understood and calibrated to an unprecedented level – I will give an example below. This has led to a constant exchange between scientists and engineers: the scientists often requesting very stringent limits on hardware response (no 'unwanted' behaviour!) and the engineers trying to meet the demands by developing new hardware or tweaking the existing one.
