We used the change in BU estimates (`Delta BU') between baseline and EOP to improve comparisons: Subtracting Delta BU from the EOP estimates corrects for expected dierences in emissions between the two deployments. In the baseline, the per-facility estimate from Solution 2 is the sum of the zones and in the EOP it is the average of all whole-facility estimates. In both baseline and EOP cases, the per-facility mean estimate from Solution 1
