LCO Red Stars

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.
