Eighty-six intrinsic 0.5-2.0 keV halo detections with unique LAB N_H.
转换链
Conversion chain
逐视线Raymond-Smith temperature和N_H吸收转换后取median/IQR。
Apply a sightline-specific Raymond-Smith temperature and N_H absorption conversion, then take the median/IQR.
- 从VizieR J/ApJ/773/92读取有halo detection且有唯一LAB N_H的86条视线;不使用原论文只作population headline的固定0.5--7范围。Read the 86 detected-halo sightlines with unique LAB N_H from VizieR J/ApJ/773/92; do not use the paper's fixed 0.5--7 population headline as the plotted interval.
- 逐视线用published Raymond-Smith temperature、LAB N_H、angr abundance与bcmc cross-sections,将intrinsic 0.5--2 flux重算为absorbed 0.5--2。For every sightline, use its published Raymond-Smith temperature, LAB N_H, angr abundances, and bcmc cross-sections to recompute absorbed 0.5--2 flux from the intrinsic value.
S_abs,i = S_intr,i × T_0.5-2(kT_i, N_H,i) - 把deg^-2除以3600变成arcmin^-2;Figure 3画86个转换值的median与IQR,p16--p84只作context。Divide deg^-2 by 3600 to obtain arcmin^-2; Figure 3 plots the median and IQR of the 86 converted values, with p16--p84 retained only as context.
S_fig = S_abs / 3600 / 10^-15
新增假设与边界
Added assumptions and boundaries
- 使用angr abundance与bcmc cross-sections复现原spectral convention。Use angr abundances and bcmc cross-sections to reproduce the native spectral convention.
