Abstract:
As part of an ongoing project to investigate the cluster formation and
chemical evolution history in the Large Magellanic Cloud (LMC), we
have used the CTIO 0.9m telescope to obtain CCD imaging in the
Washington system of NGC 2161, SL 874, and KMHK 1719 - three unstudied
star clusters located in the outer region of the LMC. We measured T1
magnitudes and C-T1 colors for a total of 9611 stars distributed
throughout cluster areas of 13.6x13.6arcmin^2^. Cluster radii were
estimated from star counts distributed throughout the entire observed
fields. Careful attention was paid to setting apart the cluster and
field star distributions so that statistically cleaned color-magnitude
diagrams (CMDs) were obtained. Based on the best fits of isochrones
computed by the Padova group to the (T1, C-T1) CMDs, the deltaT1
index, and the standard giant branch procedure, ages and metallicities
were derived for the three clusters.
Description:
We obtained images for the three selected clusters on the nights of
2004 December 17 and 18 with a 2048x2048-pixel Tektronix CCD attached
to the 0.9m telescope (scale 0.396"/pix) at Cerro Tololo
Inter-American Observatory (CTIO), Chile.
