Strumentazione prevista

SLIDE 3

Ideal Fizeau interferometric PSF

SLIDE 4

Observations at different angles are required 22.8 m 8.4 m for obtaining, by means of suitable algorithms, a unique image with a uniform resolution of a 22.8m mirror

SLIDE 5

The PSF derived from an image of the star HD-78141

First reconstructions sent on May 5, 2014 A quick reply by John Spencer, Boulder, …..

SLIDE 8

All circles correspond to existing volcanos…plus one

SLIDE 9

SLIDE 10

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.

SLIDE 11

Improved reconstruction obtained with a multi-step approach
