Minimum Detectable Polarization, expected diluted polarization, and |dlos| relative to the MDP for the MC2, Bridge B2, G0.11-0.11, and Bridge E clouds in the 4–8 keV band.
| Cloud | Energy | MDP(a) | Pmodel, diluted (b) | Pother, diluted (c) | |dlos|MDP (d) |
|---|---|---|---|---|---|
| (keV) | (%) | (%) | (%) | (pc) | |
| MC2 | 4–8 | 17.9 | 3 | 1–11 | ≥21 (*) |
| Bridge B2 | 4–8 | 17.9 | 4 | 19–25 | ≥27 |
| G0.11-0.11 | 4-8 | 12.5 | 17 | 29–30 | ≥50 |
| Bridge E | 4–8 | 13.5 | 5 | 24–39 | ≥45 |
Notes. (a) MDP in 2 Ms in the 4.0–8.0 keV band correspondent to the case of the nominal pointing. Includes effect of instrumental background. (b) Expected polarizationdegree from model of Marin et al. (2015) after environmental dilution. (c) Expected polarization degrees for other line-of-sight distances of the MC (Capelli et al. 2012) after dilution. (d) Absolute value of the line-of-sight distance that corresponds to the MDP. (*)For the MC2 cloud the MDP achievable in 2 Ms is not low enough to exclude the case dlos = 0 (Capelli et al. 2012) because it corresponds to Pother, diluted = 11%, see also Fig. 6. Hence, for this target, the lower limit given by
in the case of a non detection cannot be taken at face value.
