CFC-11 was corrected for a non- linearity in its calibration curve. The standards used were 131.4 ppt for CFC-11 and 55.6 ppt for CFC-113. A time shift compared to ozone was also applied of -10 seconds. For CFC-113 calculations, peak heights were used for calculating concentrations instead of our standard practice of using peak areas. CFC-11 was calculated using peak areas like all other flights. 1 GMTs CFC-11(ppt) CFC-113(ppt) 47027 258.2 88.2 47147 255.3 84.1 47267 259.9 82.4 47387 259.5 81.1 47627 213.6 59.0 47747 222.1 63.9 47867 212.3 63.4 47987 227.0 64.2 48227 191.7 57.7 48347 200.7 58.8 48467 199.7 61.3 48587 173.1 54.3 48827 140.4 47.4 48947 123.4 44.8 49067 114.8 44.3 49187 126.8 45.4 49427 126.2 43.2 49547 116.6 41.2 49667 110.4 40.8 49787 112.2 43.1 50027 109.6 37.5 50147 108.7 38.8 50267 109.6 39.9 50387 108.7 39.3 50627 89.8 36.0 50747 94.3 35.3 50867 107.8 41.0 50987 90.7 36.7 51227 92.2 33.2 51347 71.6 31.0 51467 73.3 31.5 51587 74.7 35.1 51827 62.5 32.0 51947 68.6 32.1 52067 66.0 32.2 52187 67.7 32.0 52427 79.5 36.2 52547 78.0 34.5 52667 78.4 35.1 52787 72.2 36.7 53027 66.7 32.8 53147 66.1 32.8 53267 64.5 34.6 53387 67.5 33.3 53627 55.3 33.0 53747 55.7 31.4 53867 55.3 33.4 53987 57.4 31.6 54227 59.4 32.8 54347 58.5 32.5 54467 56.3 31.3 54587 56.9 35.0 54827 59.2 32.5 54947 56.4 32.9 55067 57.9 33.1 55187 58.4 31.8 55427 56.7 32.7 55547 58.2 32.4 55667 57.7 33.4 55787 56.9 32.6 56027 57.5 32.5 56147 53.4 33.5 56267 34.7 26.5 56387 26.8 21.7 56627 41.2 29.7 56747 48.4 36.2 56867 48.5 29.0 56987 41.3 29.3 57227 45.7 27.1 57347 27.9 22.8 57467 46.5 29.4 57587 41.4 28.2 57827 37.3 29.7 57947 38.1 23.8 58067 35.9 28.9 58187 39.2 36.3 58427 44.7 32.9 58547 43.3 31.6 58667 47.1 31.1 58787 51.9 33.2 59027 52.8 32.9 59147 47.0 27.9 59267 32.8 28.5 59387 28.1 23.0 59627 71.3 32.4 59747 71.1 30.1 59867 97.7 38.9 59987 28.3 32.7 60227 41.8 29.1 60347 21.8 16.4 60467 28.8 21.1 60587 26.5 29.9 60827 44.3 28.5 60947 41.4 32.5 61067 38.5 29.4 61187 40.1 25.3 61427 39.4 29.4 61547 38.9 34.5 61667 42.1 32.5 61787 44.0 29.5 62027 39.0 32.3 62147 38.1 30.6 62267 38.7 31.5 62387 37.6 29.3 62627 37.9 31.2 62747 36.0 28.5 62867 34.8 31.5 62987 38.5 31.5 63227 34.6 29.9 63347 37.1 30.8 63467 34.8 29.9 63587 38.6 29.8 63827 41.9 31.0 63947 41.4 30.8 64067 38.1 28.1 64187 36.8 29.3 64427 31.8 28.9 64547 33.7 25.4 64667 31.1 29.1 64787 32.5 28.7 65027 31.8 27.0 65147 36.6 29.5 65267 44.3 32.0 65387 44.2 29.1 65627 46.6 32.6 65747 52.4 32.0 65867 55.9 33.9 65987 59.5 35.1 66227 64.0 35.2 66347 55.5 31.8 66467 54.1 33.5 66587 68.3 36.4 66827 63.4 32.0 66947 71.2 34.3 67067 67.7 35.0 67187 93.5 40.1 67427 80.2 35.7 67547 92.5 39.8 67667 62.4 37.8 67787 60.8 32.7 68027 62.0 34.5 68147 61.0 33.6 68267 58.9 32.1 68387 59.3 36.0 68627 62.6 34.2 68747 63.5 33.5 68867 67.9 35.3 68987 72.2 36.3 69227 72.6 35.4 69347 71.8 36.5 69467 73.1 36.3 69587 75.3 36.4 69827 68.6 34.3 69947 74.4 39.4 70067 71.3 37.4 70187 74.1 36.0 70427 115.4 41.6 70547 155.6 52.0 70667 196.8 59.8 70787 172.7 52.8 71027 215.0 64.4 71147 239.3 71.3 71267 205.3 65.8 71387 252.7 73.8 71627 264.6 75.7 71747 270.0 77.5 71867 268.5 74.7 71987 269.2 72.4
