charset="utf-8" From: Nina Schoetterl-Glausch In case of horizontal polarization entitlement has no effect on ordering. Moreover, since the comparison is used to insert CPUs at the correct position in the TLE list, this affects the creation of TLEs and now correctly collapses horizontally polarized CPUs into one TLE.
