... In this paper, a project aiming to allow access to data archives by means of a query-by-example mechanism is described. The basic user query would simply be the submission of an input image, either 1-D or 2-D; the system should allow retrieval of archived images similar to an input one on the basis of some ``resemblance parameter". ... A system called QUBE is currently being designed to support the QUery-By-Example paradigm in accessing astronomical data archives. ... the QUBE User Interface. ...

. To append the standard output from a command to a file use two >> (greater than) symbols followed by the name of the file. If the file does not exist it is created. For example: cat part1 > chapt2 cat part2 >> chapt2 . This creates a file called chapt2 with the same contents as part1 . It then reads the contents of part2 and appends them to the file chapt2 . The file chapt2 now contains the data from part1 followed by the data from part2 .
