II/215 uvby-beta Catalogue (Hauck+ 1998)
================================================================================
Catalogue of uvby-beta Data
Hauck B., Mermilliod M.
<Astron. Astrophys. Suppl. Ser. 129, 431 (1998)>

ADC_Keywords: Photometry, uvby, beta
Abstract:
This catalogue is an updated version of the one published in 1990
(Hauck and Mermilliod, 1990) and contains data for more than 63,300
stars in the Galaxy and Magellanic Clouds. In a first table, we
present the catalogue itself, giving for each star identifications,
coordinates (B1950), visual magnitude, and the mean value of the
photoelectric data concerning the star and the data sources.
In the second table, we give for each star, the individual
measurements. These measurements from which these values were
computed were collected from observations published until the
middle of 1996. The catalogue includes 533 references.

Note (1): numerical designation for the star identification in the
Geneva coded numbering system is described by Mermilliod
(1978BICDS..14...32M), but an updated listing applicable
specifically to this catalog is given as file 'code'.
The number may be followed by a double-star flag (byte 12)
and/or a variability flag (byte 13) if applicable.
The flag (m_LID) meanings are as follows:
D Measurement included >1 component of a multiple system
1, 2, ... Individual component of a multiple system was measured
V One or more indices display slight variability

Note (2): the flag meanings are as follows:
blank The number of observations reported in the source
reference is given
/ Number of observations not given in source reference
and is therefore recorded as 1
* The number of observations reported is a minimum;
i.e., the actual number of observations is not given
in the source reference, but it is stated that at least
the number given contributed to the published values.
