Circumstellar emission lines of Hα (top row), Hβ (middle row), and He I 587.6nm (bottom row) from the GRACES (Cols. 3, 4, 6, and 7) and Keck (Cols. 1, 2, and 5) observations. The blue curves show the spectrum of TWA 7, used as a photospheric template. The black and red curves correspond to the spectrum of JH 223 before and after removal of the photospheric contribution, respectively. The photosphere-subtracted spectra are vertically shifted for clarity.
