This directory contains material associated with the paper "High-Resolution Spectra of Ordinary Cool Stars in the K Band" by L. Wallace and K. Hinkle, which has been accepted for publication in ApJS. The user is referred to the paper for complete details. The spectral data files are in subdirectories named for the abbreviation of the object with the form xxxxx/nnnn.dat, where xxxxx is the abbreviation for the object name and nnnn.dat is the lead frequency for one of the panels of the atlas plots. Thus the file gldra/4375.dat has the spectrum of greek l (lambda) Dra beginning at 4375 cm-1 and extending to 4400 cm-1, with a small overlap at each end. The full list of abbreviations, the object names and a summary description of the file contents follows: Abbreviation Object Contents 61cyg 61 Cyg B one spectrum & transmission 61uma 61 UMa one specrtum & transmission gaboo alpha Boo two spectra gaher alpha Her two spectra gaori alpha Ori two spectra gasge alpha Sge one spectrum & transmission gccyg chi Cyg one spectrum ggcyg gamma Cyg one spectrum & transmission gl411 Gleise 411 one spectrum & transmission gldra lambda Dra one spectrum gocet omicron Cet one spectrum gzcep zeta Cep one spectrum & transmission rxboo RX Boo one spectrum & transmission sceph S Cep one spectrum solar Sun one spectrum sspot Sunspot one spectrum txpsc TX Psc one spectrum Each spectral data file has the frequency scale as the first column, and then one or two additional columns for one or two spectra or one spectrum and the atmospheric transmission function. The first entry in each spectrum column is an approximate continuum level and the second is the Doppler shift in cm-1 needed to correct the spectrum to a laboratory frequency scale. For the non-solar spectra, the next 1551 entries give the spectrum (derived from the sum of the forward and reverse scans) and the next 1551 entries give the difference of the forward and backward scans as a measure of the noise in the spectrum. A separate file, TESTPLOT, will produce a simple sample plot of the spectra.
