I assume that when I have planets that orbit a near companion star I
need to promote the orbital zone (hot, habitable, cold), to the warmer
of the two possible zones, one coming from the primary, and one
coming from the near companion.

Example:

     Primary:   F2 Ia
     Companion: M9 V in orbit 9 -- zone hot

All four potential planets orbiting the M9 companion should be 'hot'
zoned because they are in the hot zone of the F2 Giant right?
