Comments:

For ones with broad lines (>100 km/s) I gave the velocity range near the base and put 'y'. For obviously narrow ones, I did a Gaussian fit, and the three numbers are the peak counts, the centroid and the Gaussian sigma of the fit. If the width is below 20 km/s, I put a 'n' unless there seemed to be faint, high velocity wings, in which case I put 'p' For the ones wider than 20 km/s, I put 'p'.
