run019   Wasp 103   19/05/2015   22:19:45 05:13:30 3540 data FFNOC 1256.5 7014.6 u' g' z' 7 1024 x 1024 1 x 1 CDD 8C0000 -40,-40,-40 1100 W/2015A/P17 Watson trm,djab,rpa 100222   run019   Science. Looks mostly OK, with occasional seeing-related (probably) dips in transmission. Peak leavels in g' about 17000 counts/pixel.Terminated by twilight.
run018   Wasp 103   19/05/2015   22:00:20 22:17:25 179 data caution FFNOC .5 5758.9 u' g' z' 1 1024 x 1024 1 x 1 CDD 8C0000 -40,-40,-40 1100 W/2015A/P17 Watson trm,djab,rpa 100222   run018   Acquisition. Lots of focus changes. Some position shifts at start. Seeing very variable. May be worth reducing this to extend the data.
