| 2β (linked) | 0.58 ± 0.02 | = β1 | 102.9 ± 8.1 | 18.8 ± 1.6 | 0.40 ± 0.03 | 2.74 ± 0.17 | 126.2/113 (1.12) |
Notes. Parameters values for the single and double β model fits. The first row represents the single β model fit, the second row corresponds to the fit with the two β values unconnected, while the third row represents the fit with the linked β values. The first two columns report the values of β, the third and forth columns report the core radii in [kpc] units, the fifth and sixth columns report the amplitudes of the models in [10−7 photons cm−2 pixel−2 s−1] units, and the last column corresponds to the reduced χ2 values.
