GRAVITY data reduction software
Abstract
We focus on the main algorithms of the data reduction software for the second generation VLTI instrument GRAVITY. From the interferometric data and the metrology signal, the pipeline recovers the complex visibility of the science target with an absolute phase with respect to the fringe tracker target. Visibilities are then calibrated and the relative astrometry is eventually computed when possible.
