Continuum subtracted spectra of the HO 3_1,3 − 2_2,0 and HDO 3_1,2 − 2_2,1 lines toward the three sources NGC-1333 IRAS 2A, IRAS 4A-NW, and IRAS 4B. The HO spectra are from Jørgensen & van Dishoeck (2010a) and Persson et al. (2012). The green lines shows the CH₃OCH₃, and blue HO. In some of the HDO spectra (bottom two), a second line can be seen (magenta) at  1.5 km s^-1, this is from CH₃OCHO. The parental cloud velocity is shown by the dotted line (v_lsr = 7 km s^-1) and the Gaussian fits (green, magenta, and blue) to the lines are plotted along with the RMS (red). We note the different scales of the spectra toward IRAS 2A.
