\caption{Interstellar component characteristics derived from the absorption lines in the UV and optical spectrum. The ions absorption in  component 1~may be distributed over the velocities of components~A and B however the fits have been performed with one component. {  Velocities:} the listed uncertainties on $V_{\rm LSR}$ apply to relative velocities. The absolute uncertainty from the precision of the STIS wavelength calibration is about $1.2~{\rm {km~s}}^{-1}$,  absolute velocities have however been  confirmed to about $0.3~{\rm {km~ s}}^{-1}$ by the good agreement between component~C and the CO~emission in the heterodyne data, which have an absolute
precision of $0.1~{\rm {km~ s}}^{-1}$.   {  Temperature:} when possible, temperatures are derived from  the combination of $b$-values from species of different masses. The precise temperatures for components~A and~B  have been derived under the assumption that they can be identified to the two components seen in emission in the Blue Cloud H~{\sc i} spectrum.  { Column densities} (in~cm$^{-2}$): numbers in parentheses are powers of~10. All error bars are
3$\sigma$ uncertainties, except for the intervals given by the arrows, indicating and upper limit derived from a faint line and a lower limit derived from a strong saturated line. Si~{\sc ii},
C~{\sc ii} and C~{\sc ii}* profiles are saturated for all components, implying that only a lower limit could be derived for the whole absorption.}\label{tab:abscolumn}
