In the article being
corrected, I provided explicit formulas for the spherical functions and the spherical
Plancherel measure for 3 cases of ℘-adic symmetric spaces. In Case 2, an elementary
mistake in a rank one computation (Lemma 5.3) led to providing the wrong formulas
and the wrong support for the spherical Plancherel measure. Here I correct the rank
one computation and its consequences.
