Description:
This is an updated version of the original catalogue. New UBV
photoelectric measurements were added from Isserstedt (1979, 1982),
and Feitzinger and Isserstedt (1983). The remarks and origins of
photoelectric photoelectric magnitudes are not included in this
electronic version.
Photoelectric data are obtained by averaging observational values made
at 100 and more cm instruments (with weight=2) with ones made at 60
and less cm instruments (with weight=1).
Abstract:
A spectral survey has been made during the period 1971 to 1975 with
the ESO 40cm astrograph at La Silla, equipped with its normal prism,
giving an intermediate dispersion of 95Angstroem/mm at 4026Angstroem.
Long exposure plates taken directly or with an interference filter
enabled us to obtain spectral types for nearly 1600 stars. In
parallel, a V photographic survey has been carried out during the same
period with the same astrograph and has led to the determination of V
magnitudes for more that 700 stars having no previous photometric data.
New spectroscopic and photometric results as well as previous
photoelectric UBV values are given in the catalogue together with
additional remarks concerning peculiarities of spectra, V magnitudes,
and details on double and multiple systems.

Note (5): V photographic magnitude as determined from astrographic plates.
A value with two decimals means a standard error less than 0.07 mag; a
value with one decimal only means a standard error less than 0.15 mag;
a value with one decimal and a colon means a standard error higher
than 0.15 mag or one determination of low quality.

Historical Notes:
* 29-May-1989: this version which supersedes III/111 was provided by
L. Prevot (Marseille Observatory). Compared to the original edition,
UBV photoelectric data and number of measurements were recomputed.
* 01-Sep-1995 (CDS): a few misaligned decimal points and uncertainty
colons corrected in the catalog file. Documentation was standardized.
* 04-Apr-2016: added bibcodes in this "ReadMe" file;
the postiion and a Simbad name are added in the file "catalog.pos"
