This page covers everything that is part of Phase III, i.e., the data reduction, analysis  and publication. It provides, among other things, information about Gemini data, how to get them, how to reduce them and how to acknowledge them in your publications. It also offers various ways to get support from Gemini with data reduction, and to send feedbacks to Gemini on your experience as PI.
