Only authorized users have access to the full archives of both raw and reduced data from the TRES spectrograph. Knowledge of how to see those results is embedded in the tresearch script, which can be used to list results, as well as full paths to the spectra, raw images, and Postscript reduction summaries.

All searches are carried out using sky position, right ascension and declination, and it is assumed to be J2000. If you search for an object by name, tresearch looks for that name within the TRES database and uses the position of the first match. If it is not found, an attempt is made to match the object name using the SIMBAD name resolver. Moving objects which start with AST, named solar system objects, and SKY's are searched by name and ignored in position searches.

tresearch: Find entries for objects in the TRES database
          Version 1.2 by Jessica Mink, SAO-TDC, August 7, 2013
          Usage: tresearch [-v][-f][-r][-c catalog] object1 object2 ...
                 tresearch [-v][-f][-r][-c catalog]
                 @object.name.list.file
                 tresearch [-v][-f][-r][-c catalog] hh:mm:ss.ss
                 dd:mm:ss.ss
                 -c Catalog: Read from this catalog of reduced spectra
                 [/data/tres/reduced/tres.db]
                 -f: list object File names only
                 -n: No column headers
                 -p: search for plotted results
                 -r: search for Raw data
                 -s: set search radius in degrees (default is 0.01)
                 -v: list object names as they are checked

Example 1. Search for results including spectrum and best template
