CDROM/PASP/V107/P1402 Infrared Arcturus Atlas (Hinkle+ 1995) ================================================================================ Infrared Atlas of the Arcturus Spectrum, 0.9-5.3 microns Kenneth Hinkle, Lloyd Wallace, & William Livingston <1995, PASP, 107, 1402> =1995PASP..107.1402H ================================================================================ Abstract: A spectral atlas of the infrared spectrum of the bright K 2 giant Arcturus has been completed using the 4 meter Mayall telescope and FTS. The 0.9-5.3 um spectrum of Arcturus was observed at high signal-to-noise with a resolution of 100,000. Telluric lines were removed by using telluric transmission spectra generated from McMath-Pierce solar spectra or 4 meter lunar spectra. The spectrum of Arcturus was observed on two different dates selected to give large opposite heliocentric shifts. The spectra observed on the different dates have been independently corrected for telluric absorption with the result that the telluric spectrum has been effectively removed from all but the most obscured wavelengths of the Arcturus spectrum. We attempted to identify lines with central depths stronger than a few percent. Identifications seem well in hand with the unidentified lines apparently atomic in origin. The atlas is available either on an AAS CD-ROM or as an ASP monograph. Description: The atlas is contained in 310 spectral files and two line indentification files plus a file containing a list of the files and unobserved spectral regions. The spectral file names are in the form 'abnnnnn' where 'nnnnn' denotes the spectral region, e.g. file 'ab4300' contains spectra for the 4300-4325 cm-1 range. The atomic and molecular line identifications are in files 'appendix.a' and 'appendix.b'. The file 'appendix.c' is a book-keeping device used to correlate the plot plages and spectral files with frequency. See the author-supplied description in 'readme.dat' for more information.
