Notes

Jun Yang: "Onsala scan 1 should be OK. While, our scans 2 and 3 might have some problems after restarting the FS and the schedule to fix a problem related to caltsys. I saw only half bandwidth, 16 MHz , in the first subband in my auto-correlation plot. So, I skipped scan 4 and reloaded PFB firmware before scan 5. Currently, I have not seen the problem any more."
