1. Pointing plans NL (SST-CHEC) David & Remko
GRAPPA INSTITUTE
Gravitation AstroParticle Physics Amsterdam
David Berge
University of Amsterdam and Nikhef

2. Introduction
CTA requirements: 5’’ post-calibration telescope pointing precision
A challenge with guide sky CCDs
What’s more, for dual mirror SSTs, cannot view the sky and the Cherenkov camera lid from the same location
Alternative solution (see Remko’s talk for the details): measure star positions with Cherenkov camera
Real-time solution for pointing reconstruction!

3. Discussion today Exchange of ideas, towards a common discussion
Interest on our side to extend from 2M-SSTs to MSTs
To be discussed, depends on your views
Prototype plans, NL
Modified camera electronics within three months
Lab tests Amsterdam with a full slice of CHEC (2M-SST camera)
Eventually mount prototype on GATE 2M-SST prototype to measure star light
Prototype plans MST?
NB: I hear that there are discussions to move pointing reconstruction into the calibration working group (maybe first session in Warsaw)
