! Rationale: In order to facilitate the taking of a median if necessary, the
! minimum number of ifgs should be an odd number. We fear that 3
! is too small because any statistical quantities generated from
! that number are likely not to be meaningful. Seven is
! uncomfortably large because our proliferation of operating
! states during the mission will probably cause there to be a
! significant number of pixels with fewer than 7 coaddable ifgs.
! Thus, we compromise on 5.
