Status report on the GI2T interferometer

The GI2T interferometer has been recently equipped with a new beam combiner called REGAIN, including a dedicated visible spectrograph for enhanced spectral capabilities. The control system, the fringe tracking processor, the photon counting detectors as well as the data reduction pipeline have been refurbished or changed. After a long phase of qualification, the whole system is now ready for scientific operations. We will describe the main new features of the system.
