OUR "SEARCH FOR OBJECT X" EXERCISE

Project CLEA -- CONTEMPORARY LABORATORY EXPERIENCES IN ASTRONOMY -- develops laboratory exercises that illustrate modern astronomical techniques using digital data and color images. They are suitable for high- school and college classes at all levels, but come with defaults set for use in introductory astronomy classes for non-science majors. Each CLEA laboratory exercise includes a dedicated computer program, a student manual, and a technical guide for the instructor. The technical guides describe file formats, user-settable options, and algorithms used in the programs. The most advanced CLEA labs run under Windows on PC's, or on color-capable Macintosh computers.

NOTE: This website is designed primarily to distribute software to teachers and system adminstrators. It is not set up for on-line use of the exercises. If you are an individual using CLEA software in a class, you may find that downloading files and documentation is a bit involved and requires some sophistication in the use of computers. Consult your instructor if you are having difficulty downloading or installing, since he or she should be familiar with the particular circumstances of using CLEA software at your particular institution. However, for all users, general instructions on downloading and installing can be found on this website and in the CLEA technical manuals. Thanks for your interest in Project CLEA and we look forward to hearing from you with comments and suggestions!

A NOTE ON DOWNLOADING UNDER WINDOWS XP PRO if you have updated to SERVICE PACK 2 (Sept, 2004)
