# Reference for Shalika germs of GL(n)

I was reading the two Repka papers where he computes the leading and subleading Shalika germs for $$GL_n$$ and I was wondering, where are we since then? Have these germs (and the integrals) been computed somewhere? Especially if there is a reference using similar methods or something relatively simple.

The following may be a too general question, but what do we know to date about Shalika germs? What is your viewpoint of them?

Shalika germs first appeared in the papers of Shalika and Harish-Chandra. For a survey of their role in harmonic analysis on $$p$$-adic groups we refer to the beautiful article by Kottwitz (in particular, sections 6, 17, and 27).
