Facility Keywords

To aid organizations in obtaining information on the effectiveness of their Telescopes, the AAS has created a vocabulary of facility keywords for Telescope facilities for use in journal articles. The use of a common set of facility keywords across astronomical publications will make searches for Telescopes significantly easier and more accurate.

Most facility keywords are just the facility's common name or acronym but some are a combination of the Telescope's physical location and name or acronym. Authors may include additional text in parentheses after the facility keyword to cite facility instruments or Telescope configurations. For example, the Wide Field Planetary Camera II on HST would be designated as HST (WFPC2). Anyone may propose new facility keywords for facilities not currently found on the list. Contact the AAS journals' data editors, Dr. Greg Schwarz and Dr. Gus Muench at the AASTeX helpdesk, with the proposed facility keyword.

When preparing a LaTeX manuscript for submission, tag facility keywords with the AASTeX \facility macro and place them in a new paragraph following the acknowledgments. Include the word "Facility" or "Facilities" in italics at the beginning of the list. Separate multiple facility keywords with commas.

Facility Tag Samples:

{\it Facility:} \facility{HST (NICMOS, STIS)}

{\it Facilities:} \facility{KAIT}, \facility{Magellan:Baade (LDSS2 imaging spectrograph, Boller \& Chivens spectrograph)}, \facility{Magellan:Clay (LDSS2 imaging spectrograph)}, \facility{Swope (SITe No. 3 imaging CCD, NICMOS3 array)}, \facility{Du Pont (Tek No. 5 imaging CCD, WFCCD)}, \facility{Mayall (MOSAIC-1 wide-field camera)}, \facility{MMT (Blue Channel spectrograph)}, \facility{FLWO:1.5m (FAST)}, \facility{Shane (Kast Double spectrograph)}, \facility{Keck:I (LRIS)}, \facility{Keck:II (ESI)}

The table below list the 400+ facility keywords. Each keyword has a full facility name plus location, wavelength, and facility type flags to make searching easier. Click a table header to sort the list. One click will sort in descending order, two clicks will sort in ascending order, and three clicks will return to the original ordering. Hold shift and click a second row to add secondary sorting. Use the search field to find specific keywords.
