Description:
This database contains a log of the Gemini Telescope observations
since 2001, managed by the Canadian Astronomical Data Center (CADC).
The data are regularly updated (see the date of the last version at
the end of this file).
The Gemini Observatory consists of twin 8.1-meter diameter
optical/infrared telescopes located on two of the best observing sites
on the planet. From their locations on mountains in Hawai'i and Chile,
Gemini Observatory's telescopes can collectively access the entire
sky.
Gemini is operated by a partnership of five countries including the
United States, Canada, Brazil, Argentina and Chile. Any astronomer in
these countries can apply for time on Gemini, which is allocated in
proportion to each partner's financial stake.
Acknowledging Gemini and CADC data in publications:
If you have used CADC facilities for your research, you should refer
to the data as obtained "from the CADC" and include the following
acknowledgment in any publication:
"Guest User, Canadian Astronomy Data Centre, which is operated by the
Herzberg Institute of Astrophysics, National Research Council of
Canada."
