Information recovery from overlapping GAIA spectra
Abstract
Description
The RVS instrument aboard GAIA is a slitless spectrograph, so some spectral tracing overlap is inevitable. We show that this background can be accurately modeled and subtracted. Radial velocity accuracy is not degraded significantly unless the star density is higher than the value typical for the Galactic plane.
