Abstract:
We present a CCD photometric and mass function study of nine young
Large Magellanic Cloud star clusters, namely NGC 1767, 1994, 2002,
2003, 2006, SL 538, NGC 2011, 2098 and 2136. BVRI data, reaching down
to V∼21mag, were collected from the 3.5-m NTT/EFOSC2 in subarcsec
seeing conditions. For NGC 1767, 1994, 2002, 2003, 2011 and 2136,
broad-band photometric CCD data are presented for the first time.
Description:
The broad-band BVRI CCD photometric observations were carried out at
the European Southern Observatory (ESO), La Silla, Chile, in 1990
between January 10 and 13 using the ESO Faint Object Spectrograph and
Camera-2 (EFOSC-2) mounted at the Nasmyth focus of the 3.5-m New
Technology Telescope (NTT). The filters used in these observations
were standard Bessel BVR (ESO#583, 584, 585) and Gunn i (ESO#618).
The scale is about 0.23arcsec/pix
