Columns 2,3: Star name and component.

Columns 4,5: Magnitude and spectral type.

Column 6: Mean epoch of observations.

Column 7: Mean value of $\Delta\alpha\cos\delta$ in seconds of arc.

Column 8: Standard error of $\Delta\alpha\cos\delta$ in $0\hbox{$.\!\!^{\prime\prime}$}001$.

Column 9: Mean value of $\Delta\delta$.

Column 10: Standard error of $\Delta\delta$ in $0\hbox{$.\!\!^{\prime\prime}$}001$.

Column 11: Position angle.

Column 12: Standard error of position angle in $0\hbox{$.\!\!^\circ$}01$.

Column 13: Separation.

Column 14: Standard error of separation in $0\hbox{$.\!\!^{\prime\prime}$}001$.

Columns 15-17: Number of plates, number of images, and sum of weight.

Columns 18: HIC numbers, as they appear in the CCDM. Two numbers indicate that the primary has a different number than the secondary.
