Description:
Table 1 includes: the star number in the E-regions; the HD or CPD
number; the V magnitude; the B-V, U-V, V-R and R-I color indices; e,
the mean square error of the averages published (unit: 0.001
magnitude); n, the number of observations for each star; and Sp, the
spectral types (Graham, 1982PASP...94..244G 1982PASP...94..244G).
Table 2 gives similar information for the program stars. An asterisk
after the star number means that the observations were made with a
diaphragm, and a v means a variable star.
The results of the observations of the FK5 Extension stars Nx 4173,
4409, 5355, 5400, 5410, 5593, 5671, 5886 and 6056 shows that they are
variable stars; the published results correspond to the mean values
obtained from the observations.
