I commited again « 3D » imaging on visible interferometry data of the Be star Phi Persei After the work on the SgA[e] star HD62623, I updated the self-calibration algorithm to take into account the specificities of the VEGA data. The obtained images are very nice, as they clearly detail the velocity field of the Be star disk.

The top row shows the images made with the VEGA instrument, through the Halpha emission line. The bottom row shows the best model of the system made by A. Meilland.

The results, together with a wealth of new information on the system, are presented in that work .

The self-calibration algorithm is now distributed by OCA together with an installation and running documentation.
