逐M31视线积分n_e n_H并用kT=0.22 keV APEC、HI4PI phabs和observed weights。

Integrate n_e n_H through each M31 sightline and use kT=0.22 keV APEC, HI4PI phabs, and the observed weights.

  1. 采用Ueda Table 3的2005--2009、|l|>105 deg、N=36 exponential disk fit:n_e0=3.4e-3 cm^-3、R0=7.0 kpc、z0=2.7 kpc。Adopt the Ueda Table 3 exponential-disk fit for 2005--2009, |l|>105 deg, N=36: n_e0=3.4e-3 cm^-3, R0=7.0 kpc, z0=2.7 kpc.
  2. 从太阳位置沿每条M31 field sightline积分published density geometry;本项目明确补充对称|z|和n_H=n_e/1.2。Integrate the published density geometry from the Solar position along each M31-field sightline; this project explicitly adds symmetric |z| and n_H=n_e/1.2.EM(l,b) = ∫ n_e(R,z) n_H(R,z) ds
  3. 用kT=0.22 keV、Lodders APEC与field-specific HI4PI phabs将EM转为absorbed 0.5--2 brightness;以实测CGMsum statistical weights求all-field mean,14-field min--max只表示footprint。Convert EM to absorbed 0.5--2 brightness with kT=0.22 keV, Lodders APEC, and field-specific HI4PI phabs; use the measured CGMsum statistical weights for the all-field mean, while the 14-field min--max represents footprint variation only.
