Description:
We present measurements of visual double stars made by CCD imaging
from 1996 to 1999. In the article, Table 1 contains the measurements
of 51 binaries with known orbit. The residuals are discussed in the
text. Table 2 presents new measurements for 555 binaries. Angular
separation, position angle and magnitude difference are given.
