the invoking image for the current team, for values smaller or equal
distance to the initial team, it returns the image index on the ancestor team
which has a distance of <var>DISTANCE</var> from the invoking team. If
<var>DISTANCE</var> is larger than the distance to the initial team, the image
index of the initial team is returned. Otherwise when the <var>COARRAY</var> is
present, if <var>DIM</var> is not present, a rank-1 array with corank elements is
returned, containing the cosubscripts for <var>COARRAY</var> specifying the invoking
