Historical Notes:
* March 1981, by Wayne H. Warren Jr. and Nancy G. Roman at NASA/ADC
(document NSSDC/WDC-A-R&S 81-02 in "adc_doc.txt" file):
"A magnetic tape version of the Thirteen-Color Photometry of 1380
Bright Stars was received from the Centre de Donnees Stellaires (CDS),
Strasbourg (Identification Number 2052A78). As received, the spectral
types had no uniformly coded fields for searching purposes, and no
flags were included in the records to indicate remarks. In order to
improve the uniformity of the spectral types, the entire catalogue was
transferred from tape to disk at the Astronomical Data Center, and
modifications were made interactively. The spectral types were
modified such that the temperature class and subclass always occur in
bytes 12 and 13, respectively. Mt. Wilson luminosity codes (g, d, sg,
c, etc.) were shifted to occur uniformly in bytes 10-11, as was the W
in each Wolf-Rayet type. Characters which are lower case in standard
astronomical notation (e.g., Mt. Wilson luminosity codes, m and p in
peculiar and metallic-line A stars, a, b, ab in luminosity classes, e
for emission-line stars, etc.) were converted from upper to lower
case. These characters should print as normal upper-case characters on
conventional upper-case-only printers, but the use of an extended
chain printer is suggested if one is available. The asterisks were
also added as the remarks flag in byte 1 and the catalogue was
transferred back to magnetic tape.
A considerable number of stars had no MK types in the catalogue as
received. When available, these types were added from the catalogues
of M. Jaschek (1978), Kennedy (1978) and Morgan and Keenan (1973).
Additional MK types were found for stars south of -40 degrees in Houk
and Cowley (1975) and Houk (1978). Where possible, attempts were made
to resolve uncertainties and to correct obvious errors.
The order of the files (by HR number) is unchanged from the published
catalogue (Johnson and Mitchell 1975), but they do differ slightly in
that the star names present in the published catalogue (Table 7) have
never been present on the disk."
* October 1991: prepared by Lee E. Brotzmann as files on the
"Selected Astronomical Catalogs" Vol. 1 CD-ROM (1992), directory
/photom/13color
* 30-Aug-1995: documentation from CD-ROM standardized at CDS; the SpType
column has been enlarged to accommodate composite spectral types.
* 18-Jan-2017: the "notes" have been moved to a dedicated file.
