OAO2 filter Photometry of 531 stars of diverse types

<Astrophys. J. Suppl. Ser. 43, 501 (1980)>
=1980ApJS...43..501C
================================================================================
ADC_Keywords: Photometry, ultraviolet
Mission_Name: OAO-2
Description:
The catalog contains the ultraviolet photometry of 531 stars observed
with the Wisconsin Experiment Package aboard the Orbiting Astronomical
Observatory (OAO-2). The data were obtained with medium-band
interference filters and have been reduced to a uniform magnitude
system. The ultraviolet magnitudes contained in the catalog have been
published by Code et al. (1980). While the published tables contain 11
tabulated magnitudes, the machine version includes a twelfth filter
(S2F2 at 2945 A). The catalog includes cross identifications to the
numbering systems of the Bright Star Catalogue, The Henry Draper
Catalogue, and the GC, star name, spectral type, V magnitude, B-V,
U-B, references, remarks, and 12 ultraviolet magnitudes. The effective
wavelengths (for a flat spectrum source) are 4250A, 3320A, 2980A,
2965A, 2460A, 2380A, 2035A, 1910A, 1680A, 1550A, 1430A, and 1330A. For
most filters, the full width, half maximum is about 30% of the central
wavelength.

25-26: luminosity class for Mt. Wilson types;
W in byte 26 for W-R types
27-30: temperature class and subclass (generally uniform except that
Q will be found for HD174107 = V603 Aql; N and C for W-R types)
31-37: additional spectral-type information; e.g., luminosity classes,
abundance indicators, emission (e) and peculiar (p) symbols,
and additional components (e.g. + dG5)

Nomenclature Notes:
History:
* From Wayne H. Warren, January 1982, NSSDC/WDC-A-R&S 82-02:
The Catalog of OAO 2 Filter Photometry was received on magnetic tape
from the Space Astronomy Laboratory, University of Wisconsin, in
August 1981. A format description of the Wisconsin tape and a listing
of the tape contents were received simultaneously. The following
modifications were made to the catalog format in order to save storage
space and to make the records easier to process:
1. The Wisconsin tape contained two card images (160 bytes) per star.
Elimination of unused bytes and sequence numbers assigned to the
original observed objects, and merging of the card images to a
single logical record per star resulted in the present 132-byte
record length.
2. HD and HR numbers were left justified in the catalog as received.
They were converted to right justified integers so that they can
be read properly with an integer format specification.
3. The spectral types field was expanded from 11 bytes to 13 bytes
(to allow for spacing and uniformity) and temperature classes and
subclasses always occur in bytes 27 and 28-30, respectively. The
Mt. Wilson and W (Wolf- Rayet) prefixes were moved so that they
always occur in bytes 25-26 (the Mt. Wilson luminosity types and
other normally lower case characters have been converted from
upper to lower case). The spectral type for HD197989 (e Cyg),
which is K0- III, was changed from K0 III to K0 -III.
4. The HD number for V1357 Cyg (Cyg X-1) was changed from E226868
to 226868 to eliminate the character from the HD field and to make
it uniform. Certain Durchmusterung numbers, which were incomplete,
were completed and made uniform within the star name field.
5. One byte following each ultraviolet magnitude field was preserved
and those magnitudes having colons in Table 2 of Code, Holm and
Bottemiller (1980) were appended with colons in the
machine-readable catalog.
