Abstract:
The catalogue of the Geneva photometric boxes (or Golay's boxes) is
announced.
Introduction:
The Geneva photometric boxes, or Golay's boxes, are based on the
Geneva 7-colour photometry contained in Rufener's 3rd Catalogue
(Cat. II/72).
For a given star S measured in the Geneva photometry, the strict
[0.01] box is the set of stars S' whose colours are all equal to those
of S within 0.01mag; S is called the central star, and the S' are the
member stars of the [0.01] box of S. Only the boxes containing at
least 2 elements (including S) are considered.
Other definitions of the photometric boxes are used. For instance, the
"0.01" box of S contains the stars S' having |dU|=|U(S)-U(S')<=0.02,
and all other colours |dV|, |dB1|, |dB2|, |dV1| and |dG| all <=0.01.
Photometric boxes can also be defined from other colour indices
(reddening-free), or with elliptical shapes. See the definitions
used here in the "Note (G2)" section below.
