distribution in the (n_c,T_c) plane, for the a = 0, i = 85° fit. All values of bigger than 1 have been put to a high value and appear in white color in this plane to focus on the relevant configurations with . Left: using the error bar at 690 Hz used in the fitting routine. Right: reducing the 690 GHz error by a factor of 3: the region with immediately shrinks. We note that the best-fit temperature changes, while the best-fit density remains the same.
