Paper Abstract

The new Extremely Large Telescope projects need accurate evaluation of the candidate sites. In this work we present the seeing, free seeing and isoplanatic angle comparison between Aklim site located in Moroccan Anti- Atlas at the geographic coordinates 30°7'39" N, 08 18'39" W, and the Observatorio del Roque de Los Muchachos (ORM), located in La Palma, Canary Islands, at 28°45'00 N, 17°53”10 W, the both sites are pre-selected to house the E-ELT. In this work we present the seeing statistics of (Ɛ), the free seeing (Ɛ free) and the isoplanatic angle ϴ0 measurements at each site, statistics of the mentioned parameters are obtained from the whole data recorded from 09 May 2008 to 09 November 2009 using the Multi Aperture Scintillation Sensor (MASS) - Differential Image Motion Monitor (DIMM) system, compare the common data between the tow sites, more representative results and statistics are shown hereafter.
