Using uvindex, I see the frequency configuration change every 6th scan. Looking at the configurations reported by uvindex, the zoom frequencies are slightly different, but I'm unsure what could have caused this. Has it been reported before?

Re: Odd behaviour
Hi Stacy,
Not sure if this is still an issue, but could it be that this is due to the way the cabbscheduler tries to adjust the line frequencies for zoom bands based on the observatory velocity in each direction?
Cheers,
Mark
PS apologies for the delay - somehow both Jamie and I got unsubscribed from some (most?) of the forum so we didn't get notified about new posts.
