[Carpet] Carpet output

This might be that the other refinement levels didn't exist at the
iterations where you did output.  That is, I think your par file gives
level 0 present only when cctk_iteration is divisible by 16
level 1 present only when cctk_iteration is divisible by 8
level 2 present only when cctk_iteration is divisible by 4
level 3 present only when cctk_iteration is divisible by 2
level 4 present at every iteration

so if you ask for output every time cctk_iteration is divisible by 100
you'll get

cctk_iteration =   0  ==>  levels 0, 1, 2, 3, 4 present
cctk_iteration = 100  ==>  levels 2, 3, 4 present
cctk_iteration = 200  ==>  levels 1, 2, 3, 4 present
cctk_iteration = 300  ==>  levels 2, 3, 4 present
cctk_iteration = 400  ==>  levels 0, 1, 2, 3, 4 prsent

There's a discussion of this issue in section 8 ("Frequently Asked Questions")
