The CIMA Homepage


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.
