Phase plot showing the photoionization solution. Top: shows the solution for the absorption low-velocity outflow system in J1402, using the UV-soft SED and solar abundances. Each solid line represents the range of models (U_H and N_H) that predict a column density matching the observed value for that ion. The shaded bands are the uncertainties associated with each N_ion measurement. The dotted line (Al II) represents an upper limit. The black dot shows the solution, which is surrounded by χ², as the black oval. Bottom: solution for a total of six models, including three SEDs (HE0238, MF87, and UV-soft) and two abundances: solar (shown with solid lines) and super-solar (shown with dashed lines).
