GIPSY Description GIPSY is an acronym of Groningen Image Processing SYstem. It is a highly interactive software system for the reduction and display of astronomical data. It was designed originally for the reduction of interferometric data from the Westerbork Synthesis Radio Telescope, but over the last 20 years it has grown to a system capable of handling data from many different instruments. The UNIX version of GIPSY can be installed on many different architectures. Starting GIPSY At the Kapteyn institute, GIPSY is supported runs on: Alliant FX80 DECstations HP 300 series HP 700 series Sun 4 systems Convex C2 and C3 IBM RS/6000 From a "standard" environment, you start a GIPSY session by typing: gipsy This will start Hermes, the user interface of GIPSY. Hermes Hermes is the user interface of GIPSY. It enables users to do multi-tasking in an organized fashion. Users have direct control over the application programs (tasks) they run: a running task can be suspended or aborted with a simple command; various settings can be changed while a task is running. Parameters for a task can be specified at any time; if a task needs information that has not been specified yet, the user is prompted. Context-sensitive help about tasks is provided at a single keystroke. Tasks keep the user informed in two ways: they write in a log file in which the user can page and search and they can provide a one-line status message, which can be frequently updated. Hermes cannot be started directly by the user, but is started by a shell script (gipsy.csh) which prepares a number of settings before starting Hermes. Examples of control keys used by Hermes: or I : pop help screen up or down C : abort task P : enter or leave Common Output Area (COA) page mode V : page forward in, help display or keyword display Z : page back in, help display or keyword display Exit from Hermes You quit hermes by typing: END, QUIT, Q, or Z Before the session can be closed you get the prompt: Quit? Press: Y If you press Y and there are still tasks running, you get the message 'Wait for tasks to finish...'. Tasks can be aborted with ^C Help Pressing in Hermes, will display information about Hermes when no task is involved (no task name on the command line). If you type the name of a task, pressing will display information about that task. The task HELP can display or print a list of available tasks together with their purpose lines. It provides also an introduction to the input syntax for keywords. There are a couple of LaTex files (manual.tex, hermes.tex) in the directory $gip_doc, which need to be processed before they can be printed. GIDS GIDS ( Groningen Image Display Server ) is the server you need to display your 2-dimensional (sub)sets. It can be started with the task INIDISPLAY or with VIEW (which needs a (sub)set). The use of GIDS is very simple. With your mouse (and one of its buttons) you select actions (zooming, scaling etc.) in the window with the menu bars. Move the mouse pointer in one of the menu boxes and click one of the mouse buttons. An action is initiated or a sub menu appears. Hardware Applications which need access to a printer or a tape device, can generate a list of available devices on request. This list can be different on different machines.
