 \caption{Details of the absorption lines included in the atomic model
 used after converged populations were obtained. A total of 11
 transitions were treated in detail. Wavelength of absorption
 line, upper and lower level identification, excitation potential for lower level
 and oscillator strength are respectively given for each of the transitions included.\label{fabt:atom2}}
