Due to the large number of components (exceeding the number of upper-
case letters), a non-standard component designation was necessary,
hence the pairings A,Ya; A,Yb; etc. For this pair, as well as LAF 62
and LAF 71, the lower-case designations (such as Ya and Yb) do not
refer to components of a close pair.
