Using all velocity constraints:
• For Cloudy solar abundances:
C=2.45x10^-4 N=8.5x10^-5 O=4.9x10^-4
• Minimal reduced summed over 15
velocity bins = 4.2 for 44 (75-1-30) dof

Summary: Modeling AGN outflows
Analysis Key: Accurate Ionic column densities
Obstacles:- The absorber is not an homogeneous full screen!- Velocity dependent covering factor (separate for continuum and BEL)
Solutions- Data needed: Unblended doublets (CNO) and Lyman series, high S/N- Velocity dependent covering-factor and photoionization models
The Mrk 279 outflow: U~-1 (UV) ~0 (X-ray) NH~10^20
Abundances C=2.2 N=3.5 O=1.6 solar units
