Abstract:
We present high-precision VI photometry of stars from the middle of
the giant branch to about 5mag below the main-sequence turnoff in the
globular cluster Palomar 13 based on images obtained with the Keck II
10m telescope. We tabulate a complete sample of blue stragglers in
the cluster out to about 18 core radii.
Description:
We used the Echellette Spectrograph and Imager (ESI) in direct
imaging mode on the night of 1999 September 2 to observe Pal 13 at the
10m Keck II telescope at the Cassegrain focus.
