Hi, all

On the topic of looking at data with the new FPGA codes....

— good progress
— TPX FPGA code is mostly done
— about 3 RDOs done in sector 1, started moving through sector 2
— may be some issue with timing 
— but new code is running on a number of RDOs in system

— online plots are filling correctly
— hope to test much larger part of system next week

Below is the plot of clusters found in FastOffline for sector 1.

The first plot is data taken and reconstructed yesterday.
The second plot is data taken and reconstructed today.
The third plot is the online histogram for the run taken yesterday.
The fourth plot is the online histogram for the run taken today.

The good news is that the outer RDOs that weren't coming through yesterday are coming through today. Good!

I was a bit worried that the offline reconstruction _stopped_ working for the one outer RDO that was being reconstructed yesterday, but I see from the online plots that the RDO in question seems to be off today.

Also good is that while I do see fewer clusters in sector 1 than other good sectors due to the one absent RDO today, I do not see a notable dip in tracks reconstructed in sector 1 for today's data.

Thanks,
