We are pleased to announce a collaboration with two NASA Great Observatories, Chandra and SIRTF, to provide investigators with complementary ground-based observations in support of their programs. Investigators will able to obtain time on NOAO facilities through proposals for SIRTF Legacy programs and through Chandra large programs. The goal of this collaboration is to allow proposers to avoid the double jeopardy inherent in having to pass through two separate TAC processes, and to provide access to facilities essential to obtaining complementary ground-based O/IR data without regard to institutional affiliation.
Investigators applying for Chandra large programs (>300 ks) will be able to apply for time at NOAO facilities in the same proposal, with a cap of approved time at 5% of the available time at NOAO, excluding Gemini. The key criterion in the award of NOAO time is that the X-ray and optical data form a coherent database such that both sets of data are required to meet the scientific goals of the proposal. The Chandra call for proposals is expected to be issued 15 February 2000; investigators may obtain further information at the Chandra web site, http://chandra.harvard.edu.
Investigators on successful SIRTF Legacy Programs may also be allocated time at NOAO facilities. Legacy Programs are large, coherent science investigations, producing data of general and lasting importance to the broad astronomical community. Up to 10% of the time at NOAO facilities may be recommended by the SIRTF Legacy TAC. The SIRTF Legacy call for proposals is expected in June.
