Abstract:
We report deep (V∼24.0) VI CCD photometry of three fields centred in
the regions of the old open clusters Saurer A, B and C. In the case of
Saurer A, which is considered one of the oldest known open clusters,
we also provide a comparison field.
Description:
CCD VI observations were carried out with the new EMMI red arm camera
on the New Technology Telescope (NTT) at the European Southern
Observatory (ESO), La Silla, on the photometric night of 2002 December
9 and in subarcsecond seeing conditions.
