Abstract:
This paper describes the methodology currently being implemented in
the EIS pipeline for analysing optical/infrared multi-colour data. The
aim is to identify different classes of objects as well as possible
undesirable features associated with the construction of colour
catalogues.
The tools developed are used for a preliminary analysis of the
multi-colour point source catalogue constructed from the
optical/infrared imaging data obtained for the Chandra Deep Field
South (CDF-S). These data are publicly available, representing the
first installment of the ongoing EIS Deep Public Survey.
