Description
Deep optical photometry of the Fornax dSph in the B, V and I filters was
obtained using the CTIO 4-m MOSAIC II camera over 9 nights in October
2008 and November 2009. Deep photometry for the outer fields was
obtained as part of observing proposal 2008B-0397 (PI M. Mateo)
supplemented by deep pointings covering the centre of Fornax as part of
observing proposal 2009B-0157 (PI A. Saha). Our observing strategy was
to obtain several non-dithered, long (600s) exposures for each pointing,
which were stacked together to obtain the deepest photometry possible.
Short (10s, 90s) exposures were also obtained, in order to sample the
bright stars that are saturated in the deep images.
In order to ensure accurate photometric calibration of the data set,
several fields were observed in Fornax using the 0.9m CTIO telescope,
under photometric conditions. Furthermore, observations were also made
of Landolt standard fields (Landolt 1992, Cat II/183; Landolt 2007, Cat.
J/AJ/133/2502) covering a range of different airmass and colour.
Medium and high resolution spectroscopic observations are available for
individual stars on the RGB in Fornax, giving measurements of [Fe/H] and
the detailed abundance patterns of individual stars, from Battaglia et
al. 2006, Cat. J/A+A/459/423; 2008, Cat. J/MNRAS/383/183); Starkenburg
