Results from spectral analysis of Vela X in full energy range >10 GeV: summary of the properties of the LE and HE components including systematic uncertainties.
| Component | Parameter | Value | Uncertainties | ||
|---|---|---|---|---|---|
| Statistical | Morphology | Effective area | |||
| LE component | Energy Fluxa | 2.0 | 0.5 | + 0.6∕−0 | 0.2 |
| Spectral Index | 2.19 | 0.16 | + 0∕−0.21 | 0.05 | |
| HE component | Energy Fluxa | 2.6 | 0.9 | + 0∕−0.4 | + 0.4∕−0.3 |
| Spectral Index | 0.9 | 0.3 | + 0.3∕−0 | 0.1 | |
Notes. Parameter values and statistical uncertainties correspond to model A from Table 2. Systematic uncertainties due to assumptions on the morphology are evaluated from the maximum spread of parameters values with respectto models B and C in Table 2. We also report systematic errors due to the LAT effective area uncertainties (estimated using the bracketing IRFs, see Sect. 2.3 for details). (a) 10−5 MeV cm−2 s−1, integrated for energies between 10 GeV and 2 TeV.
