Figure 3最终值
Final Figure 3 value
EAGLE-NoAGN关闭AGN feedback；论文明确说它不能再现stellar-mass function或stellar-halo mass relation，因此这是physics sensitivity experiment。
EAGLE-NoAGN disables AGN feedback; the paper explicitly says it fails to reproduce the stellar-mass function or stellar-to-halo mass relation, so this is a physics-sensitivity experiment.

直接选择匹配M31 mass/radius的published bin，digitization后用共同distance-cancel与v19 APEC bridge；不做连续mass/radius rescaling。
Directly select the published bin matching M31 in mass and radius, then apply the common distance-cancel and v19 APEC bridge after digitization; no continuous mass/radius rescaling is used.
- 选择Figure 7中11<log(M*/Msun)<11.25、12<log(M200c/Msun)<14的middle panel。simulation在0.1 dex stellar-mass cells匹配Zhang sample，但未匹配observed halo-mass distribution。Select the Figure 7 middle panel at 11<log(M*/Msun)<11.25 and 12<log(M200c/Msun)<14. Simulations are matched to the Zhang sample in 0.1 dex stellar-mass cells, but their halo-mass distributions are not matched to observations.
- 读取physical 10--30 kpc radial bin中当前model的line central和shaded bootstrap band；使用calibrated log axes与exact line/fill RGB。Read the current model's line central and shaded bootstrap band in the physical 10--30 kpc radial bin using calibrated logarithmic axes and exact line/fill RGB values.
- 把digitized intrinsic 0.5--2 luminosity surface density乘共同distance-cancel factor和v19 absorbed/intrinsic APEC ratio 0.678988916；保持为单一10--30 kpc band，不插值成M31 radial curve。Multiply the digitized intrinsic 0.5--2 luminosity surface density by the common distance-cancel factor and v19 absorbed/intrinsic APEC ratio 0.678988916; retain one 10--30 kpc band and do not interpolate it into an M31 radial curve.
