The SNDICE calibrated light source (“LED-head”) is mounted on an altitude-azimuth (alt-az) motion, itself installed on the south-east platform fixed to the CFHT superior part of the dome in a overhanging position. The altitude and the azimuth motors are hold together by a right angle bracket. The azimuthal plate has been shimmed horizontally using a level. Both motors have an elementary step of 1°/400= 9”. The optical axis of the LED-head is materialized by a parallel beam, the “artificial planet” (AP), which angular aperture is 40”.
