A pointing solution for the medium size telescopes for the Cherenkov Telescope Array(pdf)

An important aspect in the calibration of the Cherenkov Telescope Array (CTA) is the pointing, which enables an exact alignment of each telescope and therefore the ability to transform a position in the sky to a point in the plane of the telescope camera and vice versa. The favoured approach for the pointing determination of the medium size telescopes (MST) is the installation of an optical CCD-camera in the dish of the telescope that captures the position of the Cherenkov camera and of the stars in the night sky simultaneously. The adaptation of this method is presented. Performance studies with simulated data and with data taken at the MST prototype telescope located in Berlin/Adlershof are shown.
