Maps of the p-H₂O 1₁₁–0₀₀ average absorbed fraction in four velocity ranges bracketing the main four diffuse line of sight cold clouds. Velocity ranges are given above each box and are marked on the low signal-to-noise spectrum observed at (0, 0) by Herpin et al. (2012), the horizontal green line marks the continuum level (in K). The color scale is clipped in the range [–1, +0.1]. The white dashed circle stands for the beam at 1113 GHz at the (0, 0) position. These maps show an almost constant signal over all positions having a detectable continuum level. The MM1 core, located inside the beam circle is barely visible.
