Abstract:
We search for new planetary mass objects by combining our deep I-band
photometry with public J-band magnitudes and by examining the nearby
environment of known very low mass members for possible companions.
Our analysis confirms the existing census of substellar cluster
members down to approximately 7MJup.
Description:
Uncalibrated I-band magnitudes for sources cross-matched with UKIDSS
J-band photometry.
