VNC stands for Virtual Network Computing. It is, in essence, a remote display system that allows you to view a computing `desktop' environment not only on the machine where it is running but from anywhere on the Internet and from a wide variety of machine architectures. For this purpose, it implements a client/server model.

SEP makes the core algorithms of Source Extractor available as a library of stand-alone functions and classes. These operate directly on in-memory arrays (no FITS files or configuration files). The code is derived from the Source Extractor code base (written in C) and aims to produce results compatible with Source Extractor whenever possible.
