Spectra of the para-H2O (111–000) line (black histogram) and the scaled para-H2O (202–111) line (blue histogram). The LSRK velocity scale is relative to the [C II] redshift from our ALMA Cycle 0 observations (Wang et al. 2013). The spectral resolution for both lines is 15.625 MHz, corresponding to ∼32 km s−1. The observations may only cover the red tail of the para-H2O (111–000) emission line.
