III/114     Spectra of Late-Type Standards, 2.0-2.5 Microns (Kleinmann+ 1986)

Spectra of Late-Type Standard Stars in the Region 2.0-2.5 Microns Kleinmann S.G., Hall D.N.B. <Astrophys. Journ. Suppl. 62, 501 (1986)> =1986ApJS...62..501K
ADC_Keywords: Stars, late-type; Stars, standard; Spectrophotometry; Spectra, infrared Description: This catalog contains a collection of K-band spectra for 26 stars with near-solar abundances, ranging in spectral class from F8 to M7 and in luminosity from dwarfs to supergiants. The spectra cover the wavelength region from 4150 to 4950 /cm and generally exhibit a signal to noise ratio above 400. Five stars here are supergiants, 15 are giants, and six are dwarfs. Data included: observation date, starting wavenumber, wavenumber increment, scale factor of relative intensity, and offset of relative intensity. File Summary:

Remarks and Modifications: A magnetic tape containing the atlas Spectra of Late-Type Standard Stars in the Region 2.0-2.5 Microns was received from Dr. Susan G. Kleinmann on April 28, 1987. The tape contained 52 files one file for each signal and noise spectrum, in VAX/VMS SAVESET format. As received, each spectrum consisted of three parts: (I) the first 412 logical records contained a "big information block" (BIB) consisting of what might be termed engineering data from the Fourier transform spectrometer. This is largely redundant information from spectrum to spectrum and most of the records were actually unused; (2) a "small information block" (SIB) of two records containing in- formation pertinent to each observation, and; (3) the array of data points. Following discussions with Dr. Kleinmann, it was mutually agreed that the BIBs could be removed from the spectra, the SIBs modified slightly for easier processing, and all the spectra combined into a single file. The merging of the data simplifies the structure and is not a hindrance to processing because each spectrum contains the same number of records and can be read with a DO statement. The elimination of the redundant information also decreased the size of the catalog by a factor of 2, a definite advantage for storage requirements and dissemination. After the above modifications were made, the data were archived for distribution. The spectra are in the same order as in Table I of the source reference.
