Title: Deep imaging of the lowest-mass members in star clusters

Abstract: We aim to obtain deep multi-band imaging of stellar clusters to identify low-mass members, including brown dwarfs. The low-mass members are most susceptible to internal stellar dynamics and external tidal stripping. The ODI/WIYN photometry will be more than 1 mag deeper than those by PS1, yielding a complete census at the faint end of the mass function of a cluster. This, when incorporated with the sample of more massive members, will enable us to quantify the effect of mass segregation and stellar evaporation. The ample field of view allows us to select in the same pointing a control field, a crucial factor in our investigation for false positive estimation.
