Description:
The catalog is a collection of spectrophotometric measurements
obtained with rotating grating scanners attached to various telescopes
at the Kitt Peak National, Mount Wilson, and Palomar Observatories.
The observations were made during the 1970s and early 1980s, both
individually and jointly, by S.J. Adelman, D.M. Pyper, S.N. Shore, and
R.E. White. All measurements were calibrated with the fluxes of Alpha
Lyrae (Vega) as presented by Hayes and Latham (1975ApJ...197..593H 1975ApJ...197..593H).
There are 1134 observations concerning 207 individual stars.

Description of file: data.dat
This file, more completely described in the "adc.doc" document,
contains all spectrophotometric observations. Each observation is
preceded by a set of two header records giving the same information as
what is contained in file "stars.dat". The observations are presented
as data pairs with wavelength (in Angstroems) and the normalized
magnitude (to 5000Angstroems) at that wavelength. The number of data
pairs in a spectrum varies depending on the instrument used and the
range, but the number of pairs is given in the second header record in
bytes 52-53. Thus, a spectrum can be read with the following FORTRAN
statements:
character*10 name
real*4 lam(50),mag(50)
read(5,'(9X,A10)') name
read(5,'(51X,I2)') nwl
read(5,'(5(F7.0,F7.3))') (lam(i),mag(i),i=1,nwl)
Note: Differences from published values of 0.001 magnitude may result
from different ways of rounding off. Some scans of possible values are
given, while only the averages have been previously published.
Note on Beta Lyrae Data (spectra 918 to 922): for the three nights for
which the scans cover the spectral region 3300-7102 Angstroms, nine
scans of the standard stars 58 Aql (1), 29 Psc (1), HD 15318 (4), and
Eta Hya (3) were obtained on each night. For the other two nights,
spectrophotometric standards using the values of Breger (see Cat.
III/48), as supplemented by Taylor, were used. These scans were
obtained on the same nights as the data in Papers 14 and 21.
History:
* January 1990, Wayne H. Warren (from "adc.doc" file):
The text and data files were prepared initially at The Citadel by
S. J. Adelman following discussions about an acceptable structure
and format for the catalog. Proofreading was done with the assistance
of Carol J. Adelman and Jeffrey A. Garret. The data were transferred
to the Astronomical Data Center via BITnet. Extensive checks of the
header records resulted in minor corrections and changes, e.g., to
correct shifted data and to insert mixed case characters where
appropriate.
* May 1998, F. Ochsenbein:
the files "stars.dat" and "refs.dat" have been created from the
"data.dat" headers and the "text.txt" file. The positions were
extracted from the SIMBAD data-base.
