  In his Ph. D. thesis, C. Lehr offers an algorithm which gives the stable
model for p-cyclic covers of the projective line over a p-adic field under the
conditions that the branch locus whose cardinal is m+1 has the so called
equidistant geometry and m<p. In this note we give an algorithm also in the
equidistant geometry case but without condition on m. In particular we are able
to study the reduction at 2 of hyperelliptic curves with equidistant branch
locus.
