Reconstruction of post-adaptive images of Io observed with LBTI and KECK M. Bertero. P. Boccacci e A. La Camera DIBRIS, Università di Genova ADONI2016 - Firenze 12-14 Marzo 2016
Strumentazione prevista LBC Red/Blue (2006-7) LUCIFER 1&2 (2008-9) LBTI (2009) LINC-NIRVANA (2009) PEPSI (2009) MODS 1&2 (2008-9)
Ideal Fizeau interferometric PSF
Observations at different angles are required 8.4 m 22.8 m for obtaining, by means of suitable algorithms, a unique image with a uniform resolution of a 22.8m mirror
The PSF derived from an image of the star HD-78141
The 7 images of Io observed with LBTI, December 24, 2015
First reconstructions sent on May 5, 2014 A quick reply by John Spencer, Boulder, …..
All circles correspond to existing volcanos…plus one
Proiection on the lat-long plane of both the local reconstruction and the Voyager image of Loki and their superposition; due hot spots, presumably one permanent ad the other due to a ‘’resurfacing’’ process.
Improved reconstruction obtained with a multi-step approach
Identified volcanos and artifacts
