Equivalent width data for NGC 2264 sample

Equivalent widths
The equivalent widths of the stars in the NGC 2264 sample are shown in comparison with the standard equivalent widths measured for main sequence stars (using the data of Jacoby, Hunter, & Christian (1984) as the main sequence reference). Stars later than K have emission lines, while a transitional group of what I called "anemic stars" have absorption lines which are narrower than expected for main sequence stars.
