00:40:59.7 40:36:53.6 Velocity: -524.72 Type: HII Log NII/Hα: -0.664 Log OIII/Hβ: 0.008 Log SII/Hα -0.959 Log OI/Hα -2.472 Hα FWHM : (4.700) m475: vmag Log Mass: mass Comments: For ones with broad lines (>100 km/s) I gave the -524.72 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 -524.72 wings, in which case I put 'p' For the ones wider than 20 km/s, I put 'p'.
