CIMA is the main user-interface and top-layer control software for running astronomical observations at Arecibo Observatory. CIMA provides the observer with a graphical user interface making it easy to control the telescope, the receivers and the back-ends. The CIMA system also includes a data quick-look facility, monitoring windows and other tools useful for an observer.

The system was originally developed for Arecibo by Jeff Hagen. The responsibility for CIMA was taken over by Mikael Lerner in October 2004. The name CIMA is (was) an acronym standing for Control Interface Module for Arecibo, although it nowadays is more often thought of as just a name in itself. Although not having any meaning in English, CIMA in Spanish means "top", "peak" both in a figurative and in a literal sense.

CIMAFITS is the name for the Arecibo FITS-file format. CIMAFITS is based on the BDFITS (Big-Dish FITS) collaboration with Green Bank building upon the SDFITS (Single-Dish FITS) format and the WCS (World Coordinate System) standard for FITS-files.

CIMA logs

There are five log pages available which reflect changes made to the CIMA system since October 2004:

• The CIMA version log which lists the differences between the different CIMA versions.
• The CIMA version history log which lists the dates when the different CIMA versions have been updated.
• The CIMA user's log which chronologically lists changes made to CIMA that may be relevant to an observer.
• The CIMA engineering log which lists engineering changes made to CIMA that probably are of less interest to an observer.
• The CIMAFITS log which lists changes made to the Arecibo FITS-format and the FITS-writing back-ends.

CIMA development

These pages contain material used by the CIMA users working group which has been set up to discuss and decide on future improvements of CIMA.

• The CIMA users working group - which plans the future of CIMA.
• The CIMA to do list - containing a list of problems and suggested improvements.

Old CIMA pages

These pages have all been assembled by Jeff Hagen and refers to CIMA before October 2004. These pages are thus not up-to-date but still contains some useful information about CIMA. As the information gets updated it will be moved to some of the CIMA pages mentioned above.

• CIMA primer - an introduction to the AO user interface.
• The WAPPs - the Wideband Arecibo Pulsar Processors. This is very much the CIMAFITS log up to October 2004.
• WAPP spectral line FITS document - a description of the CIMAFITS format.
• WAPP spectral line observing - some notes.
• Van Vleck correction on the WAPPs - 3 and 9 level Van Vleck corrections.
• The aostatus display window - installation and example.
• Continuum observing at the Arecibo 305m console - instructions by Phil Kronberg and Chris Salter.
• The WAPPMASK FITS-header parameter - an explanation of its contents.
• Apparent coordinates - an explanation.
