IRIS system is a program complex for processing and analysis of large arrays of research data (in particular, images). IRIS is a researchers toolbox to decide a lot of concrete problems. IRIS is oriented, first of all, on the researchers - scientists, engineers, graduate students, students etc. Main features of IRIS are simplicity of use, flexibility, possibility of integration with other applications (advanced OLE and DLL-interface). Native formats, which are processed by IRIS, are: - FITS (Flexible Image Transport System); - SBIG (uncompressed image files for Santa Barbara Instrument Group (r) CCD matrixes ST-4X/5/6/7/8); - BMP (8-bits standard Windows Bitmaps). There is the possibility to include support of practically any data formats without recompiling of IRIS. System IRIS consists of the three component-applications: 1. IRIS-integrator (IrIn) - system shell, command center, data flows control, work with data kits, processor of built-in macrolanguage Bastis, kit of standard image processing procedures. 2. WisA - image visualization and operative analysis. 3. HeadEdit - viewing and editing of accompanying information (in particular FITS, SBIG - headlines), working with data files formats, system journal keeping.
