Abstract
For a rigid space , we answer two questions of de Jong about the category of coverings which are locally in the admissible topology on the disjoint union of finite etale coverings: we show that this class is different from the one used by de Jong, but still gives a tame infinite Galois category. In addition, we prove that the objects of (with the analogous definition) correspond precisely to locally constant sheaves for the pro-etale topology defined by Scholze.
