What is the difference between a Legacy Science project and a General Observer (GO) investigation?
Posted by Elena Scire on 12 January 2009 10:10 AM
There are three characteristics that distinguish the Spitzer Legacy Science Program from GO investigations:


  • They must be large coherent science investigations, not reproducible by any reasonable number or combination of smaller General Observer programs;


  • They must be programs whose scientific data, upon archiving, are of general and lasting importance to the broad community; and


  • All raw and pipeline-processed data must enter the public domain immediately, thereby enabling timely and effective opportunities for follow-on observations and for archival research, with both Spitzer and with other observatories.

If a proposed investigation did not meet all of the these requirements, it was ineligible for consideration as a Legacy Science project. Legacy Science programs were a part of the Spitzer cryogenic mission, and are not available as part of the Spitzer warm mission.
