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.
