GAIA accuracy on radial velocities assessed from a synthetic spectra database
GAIA accuracy on radial velocities assessed from a synthetic spectra database
Spectrograph aboard the GAIA satellite operates in the near-IR, in the 8490–8740 Å window accessible also from the ground. The most important parameter yet to be determined is the spectral resolution. Realistic estimates of the zodiacal light background are obtained and a total of correlation runs are used to study …
