Another consideration:  If the satellite gets put up at the
wrong longitude, it takes a while to slew it around.  So it
is best to put it up at the right longitude if possible.  That
means the transfer orbit needs to have its apogee at the
correct longitude, over the equator.  This in turn means that
the boost into the transfer orbit must occur 180 degrees from
the desired longitude, while crossing the equator.  So if the
shuttle gets off the pad late, it may need to delay release
of the satellite for nearly an extra day.
