Abstract

The NICI (Near Infrared Coronagraphic Imager)/Gemini South Campaign is the most ambitious direct extrasolar planet imaging campaign to date, achieving median contrasts of 13 and 15 magnitudes at 0.5 and 1.0 respectively. Starting in December of 2008, we have begun looking for both methane-bearing candidates (T< 1400 K) and non- methanated substellar companions around several hundred nearby stars chosen on the basis of youth, proximity, spectral type, etc. Here, I present the data reduction techniques ...
