HIGH-RESOLUTION SPECTROSCOPY OF Q1100-264 AGAIN

The results of echelle spectrometry with resolution less-than-or-similar-to 9 km s-1 of the Ly-alpha-forest region of Q1100-264 are described. The Ly-alpha-forest systems show a range of Doppler parameters from 12 km s-1 to about 80 km s-1, with rather large uncertainties for the low H I column density systems particularly. Few of these systems have low Doppler parameters, and there is no significant trend of Doppler parameter with H I column density, in contrast with the results of Pettini et al. from the study of a different quasar. The six heavy element systems with lines in the observed spectral region are all found to have complex velocity structure, on scales ranging from less-than-or-similar-to 10 km s-1 to approximately 150 km s-1.
