Description:
The previous compilation of UBV data (Mermilliod 1986a,b,c)
contains the UBV photoelectric observations published between 1953
and 1986. The present supplement adds the data published between
1986 and the end of 1992 which represent 25639 new UBV data. The
corresponding references were numbered in continuation of the main
catalogue and go from number 1603 to 1784.
See http://obswww.unige.ch/gcpd/ph01.html for a description
of the UBV photoemtric system.

Note on rem:
the components are indicated by an extra digit;
"D" stands for double
"S" designates supplementary stars (example in Praesepe,
KW 250 and KW 250s both exist)
Note on n_UBV:
S = Standard star
/ = Number is unknown
* = the minimum number of measurements is given
