Correction to “dielectric measurements in a shielded open circuit coaxial line”

In the above paper,¹ there is a misprint which should be corrected as follows: Below (11), use the following expressions for d of a center conductor with a hemispherical end: d1 = dp − a(0.42 ± 0.02), in a 50-Ω line d1 = dp − a(0.36 ± 0.08), in a 75-Ω line.
