IRAM NOEMA (NOrthern Extended Millimeter Array) Observation Log

This table contains the IRAM NOEMA (NOrthern Extended Millimeter Array) observation log. The Institut de Radio Astronomie Millimetrique (IRAM) was founded in 1979 and is operated as a French-German-Spanish collaboration. Its partner institutes are the CNRS (Centre National de la Recherche Scientifique, France), the MPG (Max Planck Gesellschaft, Germany), and the IGN (Instituto Geografico Nacional, Spain). The principal activity of IRAM is the study of cold matter (molecular gas and dust) in the solar system, in our Galaxy, and out to cosmological distances, in order to determine its composition, density, mass, temperature, and kinematics. IRAM operates two observatories at millimeter wavelengths which are open to the international astronomical community: the 30-m single-dish telescope on Pico Veleta (2850 m), Spain, and the six-antenna interferometer on the Plateau de Bure (2550 m) in France. Both sites are at high altitude to reduce the absorption by water vapor. The observatories are supported by the IRAM offices and laboratories in Granada and Grenoble. The observation log included here concerns NOEMA, the NOrthern Extended Millimeter Array, and summarizes the observations made there. NOEMA is the successor to the Plateau de Bure observatory. During its history, the observatory at the Plateau de Bure underwent several track extensions, received additional antennas (all of 15-m diameter and of similar construction to the first ones) and technical upgrades. From a three-antenna interferometer with a maximum baseline of 288 meters in 1988, it has evolved to a eight-antenna array with baselines up to 760 meters in 2016. With the inauguration of the seventh antenna in September, 2014, the observatory started its transformation into NOEMA. More information about NOEMA is <a href="http://www.iram.fr/IRAMFR/GILDAS/doc/html/noema-intro-html/noema-intro.html">available at the IRAM web site</a>. The observation log for the 30-m telescope is available as the HEASARC database table <a href="/W3Browse/ground-based/iram30mlog.html">IRAM30MLOG</a>, and the observation log for the Plateau de Bure Interferometer is available as the HEASARC database table <a href="/W3Browse/ground-based/irampdblog.html">IRAMPDBLOG</a>. For more information on IRAM, see <a href="http://www.iram-institute.org/">the IRAM home page</a>. This table was originally ingested by the HEASARC in August 2017. It is based on the CDS table B/iram/, files noema.dat and noema_pi.dat. It was last updated in September 2020, based on an updated version of these tables which were also obtained from the CDS.
