PAVO is an integral-field-unit for measuring spatially-modulated fringes in the pupil plane. It spectrally disperses light over a 630-950 nm bandwidth (R ~ 100). PAVO can combine the light from two to three telescopes. On the longest baselines, PAVO can achieve a resolution of 0.2 mas.
Currently PAVO is commissioned for two-telescope operations. The data reduction pipeline is not yet calibrated for three-telescope data.
