Best-fit parameters for Ks wide-field image, under different circumstances that may affect systematics.
Notes. We note that all the formal uncertainties of the best-fit parameters are ≤1%, with the exception of row 8, which has significantly larger formal uncertainties due to the large reduced χ2. The χ2 listed here are smaller than the ones listed in Table 1 because the fitting range is different here (R ≤ 0.5 pc compared to R ≤ 1 pc in the main body of the paper; see discussion on the change of the projected power-law in Appendices B.6 and 4.4). Therefore they are not listed in this table, which serves to explore systematic uncertainties, which dominate the error budget.
