Astrometric and photometric characterization of the PRISMA fish-eye cameras for meteor observations

The project PRISMA is the first network for systematic surveillance of meteor and atmosphere. More specifically this thesis is about the astrometric and photometric characterization of PRISMA cameras and also the computation of meteoric trajectories. In the first and second chapter there is a general overview of meteor phenomena and a theoric description of meteoroid interaction with the atmosphere. At the beginning of the third chapter there is a description of the project, what it deals with and who partecipates. Then there is the general specification of the Basler camera and the tests that have been conducted on a single camera. These tests have been useful to understand how temperature variations could affect the response of the camera and which magnitude the camera works better. In the fourth chapter it can be find the procedure to clean and subsequently to obtain the catalogs from the images taken with the Basler camera. Then it is explained what is the procedure to arrived at an astrometric solution with the software Scamp. Afterwards the obtained results are illustrated. In the last chapter, the dynamic calculation is explained to get the meteoric trajectory from the astrometric images taken from two stations of PRISMA network, Lignan and Torino.
