Total fluxes of the reconstructed 0.511 MeV images with different algorithms.
| Algorithm | Total flux (cm−2 s−1) | |
|---|---|---|
| Thin disk model | Thick disk model | |
| MAP RL | 2.91 × 10−3 | 2.72 × 10−3 |
| RL | 4.26 × 10−3 | 4.33 × 10−3 |
| Noise-damping RL | 4.11 × 10−3 | 4.17 × 10−3 |
| Model | 2.61 × 10−3 | |
Notes. The model flux shown here is the integrated flux from 0.509 MeV to 0.513 MeV of the assumed 0.511 MeV models. Since our assumed model has intrinsic line widths (FWHM) of 2 keV and 3 keV for the bulge and disk components, respectively, the reconstructed flux is compared with the model flux within the bin width of the response matrix.
