I have some updates/corrections for the list from my recent travels...
ATL
In the main checkpoint, the lanes with the MMW are actually 12-15 (not 13-16), and 21-22 (lanes 23 and 24 do not exist). In the south checkpoint lanes 2/3 and 4 have the MMW (a total of 2 MMW devices) and lane 1 is WTMD-only.
SRQ
There are 3 MMW devices, which means that each pair of lanes has the NOS.
