The angle range is related to the number of degrees across the sky the radio telescopes beam covered (related to Earth rotation rate and slew rate of the telescope beam). When AR is low the telescope beam didn't move much (pointed to nearly the same spot in the sky during that WU) and _all_ the processing (FFT's) can be done. When AR is high (meaning the telescope beam covered a large angle range (distance) across the sky during the WU) the processing must be reduced (not all the FFT's can be completed) and thus run time is reduced ...

Subject: Work units taking longer to crunch

I've noticed that occasionally I get a work unit that takes apporoximately twice as long to complete.  I've checked my setispy log and found that wu's that take longer to crunch have an "angle range" that is lower/smaller then usual.  Usual being >.4  The more time consuming wu's are around .003 to .03  For the more scientifically inclined...what does this mean.
