Globally measured d t ⁴⁻³ and d t ⁵⁻⁴ values. (a) Ray paths for the d t ⁴⁻³ and d t ⁴⁻³ measurements. The CMB piercing points are of S4KS. Thick lines show the ray paths for which both d t ⁴⁻³ and d t ⁵⁻⁴ are measured, while thin lines show the ray paths for which only d t ⁴⁻³ is measured. Other details are the same as Fig. 6a. (b) Measured d t ⁴⁻³. Details are the same as in Fig. 6b. (c) Measured d t ⁵⁻⁴. Details are the same as in Fig. 6b. (d) Total residuals for d t ⁴⁻³. Details are the same as in Fig. 6c
