Descripción
Ground-based observations were used to analyze the CMD over a wide
spatial field in the B and V bands and to estimate the atmospheric
parameters of the spectroscopic targets. In addition, we used
ground-based U images available for a smaller field, and images taken
with the Advanced Camera for Surveys onboard the HST (ACS/HST) in the
F606W and F814W bands to make our study of the double SGB extend from
the ultraviolet to the infrared spectral regions. The HST ACS/WFC images
were obtained under program GO-10775 (PI Sarajedini).
