Paper Abstract

AMBER, the near-infrared VLTI focal instrument, will produce a huge amount of data dedicated a large astronomical community, even not experts in interferometry. It will offer several observing modes, involving 2 or 3 apertures, of either 8 m or 1.8 m, providing various spectral resolution, sensitivity or accuracy. We present here the corresponding data structure and processing scheme. This scheme is designed so as to provide the observer with useful on-line indicators of the observation quality and to eventually produce calibrated (i.e. instrument and conditions independent) complex visibilities, for each observing mode. It will also enable the observer to re-do part or the whole data processing flow. Finally, the specificity of this data structure and data flow or, on contrary, its usability for other interferometric instruments will be discussed.
