(A) As of June 2013 SASSy was approved to utilise band 3 weather in situations where no other legacy survey requires it. The time was subtracted from their band 4 allocation.
\n(B) As of June 2013 JPS has been approved to utilise band 4 weather in situations where no other survey legacy requires it. The time will be subtracted from their band 3 allocation.<\/p>\n
