Description:
The Photometric Atlas of the Spectrum of γ Tauri 5186-8700Å
(gamma TAU; Appelquist et al. 1983) lists normalized intensity and
wavelength at 22,725 points along the spectrum of the K giant γ
Tauri. This atlas supplements the atlas already completed for the
blue-green region by Gratton et al. (1975). The atlas is "based on
spectrograms of dispersion 4.9Å/mm obtained with the 1.2m telescope
and Coude spectrograph of the Dominion Astrophysical Observatory" and
is the first of a set of four (including α Boo, ρ Boo, and
δ Boo A) intended to illustrate the effects of temperature and
metal abundance variations on the spectrum. The catalog is in five
files: the first four files cover the ranges 5186-6004, 6000-7004,
7000-8004, and 8000-8700 Angstroms, respectively, and the fifth file
lists the entire range without gaps or overlap.

Remarks and Modifications:
The Photometric Atlas of the Spectrum of γ Tauri 5186-8700Å
was received by the Astronomical Data Center (ADC), NASA Goddard Space Flight
Center, from the Centre de Donnees Astronomiques de Strasbourg (CDS), in
September 1983. The catalog was in five text files, formatted as described
above. Eight bytes on the beginning of each record containing the file
identification were removed, and trailing blanks were trimmed by means of an
editor to reduce the record size from 76 to 68 bytes. A FORTRAN program was
run to check the validity of each field according to its data type and value.
The original documentation was scanned and incorporated into this ReadMe file.
No attempt has been made to reorganize the data. Currently four data points
are on each record.
