I have a time series, I want to operate (read only) on all the items  
with a particular day_of_week.  What is an efficient way to get at  

I've tried:

		desiredDates = [dt for dt in myTS.dates if dt.day_of_week ==  

                 desiredSeries = myTS[desiredDates]

but that seems quite slow.  The second line is the one which is taking  
all the time.  Is there a faster way?  I don't need a copy, just a  
view, if that helps.
