Title: Successes and challenges of Large Programs at CFHT.

Presenter: Daniel Devost


CFHT has been conducting projects that involve a significant amount of telescope time coming from multiple partners and spread over several years since the start of the Canada-France-Hawaii Legacy Survey in mid-2003. Since then, a total of 16 Large Programs that totaled more than 1400 Nights allocated. LPs are expected to have a high scientific return but are hard to complete because of the need for good image quality and dark skies. CFHT’s QSO mode allows for great flexibility for the scheduling of the programs and a high completion rate. It is however difficult to complete deep extragalactic surveys. These often require good weather conditions and dark time which are in high demand. I will present the scientific impact of our different LPs and describe the difficulties encountered during observations of these programs.
