Blue sideband rows raise packet index by one with the same drive energy. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
Blue sideband raises packet 0
The blue drive is ten joules and raises the packet from 0 to 1.
Edrive=10J,n:0→1,a=1
Blue sideband raises packet 1
The blue drive is ten joules and raises the packet from 1 to 2.
Edrive=10J,n:1→2,a=1
Blue sideband raises packet 2
The blue drive is ten joules and raises the packet from 2 to 3.
Edrive=10J,n:2→3,a=1
Blue rows move upward with the same ten-joule drive
The start packet changes, but the relation gap plus spacing stays fixed at ten joules and every displayed row is accepted.
