First, we compute the various physical quantities for the proton target case, such as the total and differential cross sections, $t$-momentum transfer distribution, and $K^-$ decay-angle ($\\phi$) distribution. It turns out that $D_{13}$ plays an important role to reproduce the electroproduction data properly.
