Spatially resolved galaxy relation between the dispersion from the SFR calibrations for [Cii] (top) and [Oi]₆₃ (bottom) as a function of FIR color, i.e., PACS 100 μm/PACS 160 μm. The legend explains the symbols used for different galaxies with the color bar indicating the oxygen abundance. Representative error bars are indicated in the lower left corner. Uncertainties on the SFR include the errors on each of the SFR calibrators (GALEX FUV, MIPS 24 μm) as well as the average scatter in the reference calibration (see Table A.1). Uncertainties on the PACS line ratios incorporate the errors due to map-making as well as calibration uncertainties (5%). The Spearman’s rank correlation coefficients are presented in the top right corner. In parentheses, we show the dispersion for the complete galaxy sample, i.e., galaxy regions that have >5σ detections for all three lines [Cii], [Oi]₆₃, and [Oiii]₈₈.
