LCO Red Stars

|CTIO Home| |IR Standards|


This page contains information on standard stars currently being used at CTIO with our facility imagers. The photometry data are from the lists compiled for RED stars on the same system as the new faint HST/NICMOS standards (the LCO system). We are grateful to Eric Persson, and his collaborators David Murphy, Wojciech Krzeminski, Miguel Roth, and Marcia Rieke for making these data available for the CTIO www pages.

These data may be useful in making and checking color transformations between systems. Some of the same stars were originally observed on the CIT/CTIO system.
