corrections to July 2006 log: (1) GN Sept. 2, 2006: Files 33032 - 33302: The chopper throw (295-300) is entered into the integration time column. The integration time is not given, but since the interval between cycles is 6-8 minutes for all the DR 21 files in this batch, just as it was the day before and the day after, we can safely assume that the integration time was the same as the day before and the day after, namely 90 seconds per hwp position.
