Plot of the ratio of objective‐prism flux (in counts) to spectroscopic flux vs. Hα + [N II] equivalent width measured from the follow‐up spectra. Data from three different observing runs on two different telescopes are plotted: squares, MDM 2.4 m in 1998 May; triangles, MDM 2.4 m in 1999 April; circles, KPNO 2.1 m in 1999 May. See Gronwall et al. (2001b) for details of the spectroscopic observing runs. The solid line indicates the median ratio. Five galaxies with EW > 250 Å lie off the diagram to the right.
