Caption: Figure 9.
Top: spatial profiles of column density (black) and rotational temperature (red) for H2O in E3 with the slit positioned along the projected Sun–comet line. The stellar PSF (dashed) is also shown, along with the orientation of the slit. The black bar indicates the ﹩0\mathop{.}\limits{^{\prime\prime} }7﹩ seeing. Bottom: spatial profiles of H2O column density and rotational temperature in E3 with the slit oriented perpendicular to the projected Sun–comet line.
