II/169/ Observations in the Geneva Photometric System 4. (Rufener 1988)
Catalogue of Stars Measured in the Geneva Observatory Photometric System,
4th edition
Rufener F.
<Geneva Observatory (1988)>
ADC_Keywords: Photometry, Geneva
Description:
This catalog is a successor to an earlier edition (Rufener 1981). It
is a compilation of photoelectric measurements made in the Geneva
Observatory seven-color photometric system. This edition contains data
for 29397 stars. Observations on the Geneva system are made through
three wide- and four intermediate-band filters extending from about
350 to 570 nm. The indices of the system measure such parameters as
effective temperature, luminosity, blocking by metallic lines, the
size of the Balmer discontinuity, and the importance of line blocking
in the 380-480-nm wavelength range. Taken together, the photometric
indices allow a three-dimensional representation of stars in the A0 to
G5 spectral range. Additional details can be found in Golay (1973).
The catalog includes star identifications (HR, HD, DM); equatorial
coordinates (B1950.0); the normalized magnitudes of the system (U, V,
B1, B2, V1, G); the color indices (B1-B2, B2-V1, V1-G); the parameters
d, delta, g, m2; and the V magnitude on the UBV system. The numbers of
measurements and standard deviations are included separately for the
colors and the V magnitude.

Note on m_HD:
For components of multiple stars we added the suffix
A, B, C... Usually when we know that two or more components
are measured together a remark is made, D for optically double
and B for spectroscopic binaries in column Remarks.
Note on DM:
The HD pratice is BD for zones +89 to -22, CoD for zones -23 to -51,
and CPD for zones -52 to -89.
For multiple stars we added the suffix A, B, C ...
Note on Remarks: the following symbols are used:
D: Optical double star not separated during the measurement
B: Spectroscopic binary
V: Variable
R: Reference to a note at the end of the catalogue.
S: Star used as a standard.

History:
* The files were supplied to CDS in 1991 by Noel Cramer (Geneva);
some records were realigned to fit in the common format.
