Electron density vs. temperature for dereddened line ratios from the SOR. The data are from the 2002 FORS1 spectrum. The shown lines are: [N II] λλ6548,6581/λ5755 (solid), [O III] λλ4959, 5007/λ4363 (dotted), [S II] λλ4069, 4075/λ6716,6731 (dotted-dashed), and [S II] λ6716/λ6731 (dashed). Each ratio is represent by three curves where the outer curves are for the 1σ statistical uncertainty.
