Examples of photospheric line subtraction for the Paβ line for CQ Tau (upper panels) and RY Tau (lower panels). The red lines represent the photospheric templates. The left and right panels show, in black lines, the observed and photospheric-subtracted spectra, respectively. The green vertical lines mark the intervals for the equivalent width measurement. The equivalent widths of the emission line before and after the subtraction are also indicated.
