| Abstract |
This report discusses the handling of the experimental data for each visit to each city during the surveillance program. For each visit to each city, two repeat runs are made on each of 10 cars of the same make without an exhaust control device and on each of 10 different cars of the same make with an exhaust control device. Three makes of cars are tested; there are thus 120 separate runs for each visit to each city. The methods and computer programs described are used to process the separte runs and to prepare certain comparison tables. |
