An Infrared Spectral Atlas of Arcturus for the Range 10750 - 11500 cm-1 (8690 - 9300 A) Lloyd Wallace and Kenneth Hinkle Kitt Peak National Observatory, National Optical Astronomy Observatories lwallace@noao.edu, khinkle@noao.edu NOAO is operated by the Association of Universities for Research in Astronomy, Inc. under cooperative agreement with the National Science Foundation. The electronic version of this atlas consists of 8 ASCII spectral files and one line identification file. Each spectral file contains the spectra used to construct two pages of the atlas plots. The spectrum may be readily plotted from these files using standard graphics packages, e.g. MONGO. The hard copy atlas pages were prepared using MONGO. Below we give a sample MONGO program for producing a simplified atlas page. The spectral files are labeled abnnnnn, where nnnnn is the wavenumber of the middle of a two page set. For example file ab10950 contains spectra for the 10900-10950 and 10950-11000 cm-1 pages. The file structure is as follows: column 1 contains the frequency scale in wavenumbers column 2 is the derippled, observed Arcturus spectrum column 3 is the telluric spectrum column 4 is the ratioed Arcturus spectrum after smoothing and continuum adjustment. Note that there are numbers in this column even for spectral regions where information has been blocked by opaque telluric lines. These regions are not plotted in the hard copy version. The atomic and molecular line identifications are listed separately in the file linelist. =============================================================================== ! MONGO instructions for producing a simplified atlas page. ! Sample spectral plot is for the two pages, 10900-10950 and ! 10950-11000 cm-1 pages. Each plot covers 50 cm-1 with a 3 cm-1 ! overlap on each end. ! Change the output device, input data file name, and plot limits ! as needed. Then run as an INPUT file in MONGO. define doit !
