Bank D crashed during configuration and did not reconfigure and activate for scan #1 (Mode 1)
Scan #1 is Mode 1
Can't see HI line. Lot of RFI spikes
Scan #2 is Mode 2
Can't see HI line. Lots of RFI spikes
Scan #3 is Mode 3
Weak detection this time
Scan #4 is Mode 4
Getting a better detection now
Scan #5 is Mode 5
Good detection, but line is broad. I might be using too small a velocity throw.
Scan #6 is Mode 6
Good scan. Same situation as above.
Scan #7 is Mode 7
Looks good, and velocity throw is fine for the source of interest, but Galactic HI is close to the source line with the chosen switching velocity. So it looks kind of nasty.
Scan #8 is Mode 8
Same as above
Scan #9 is Mode 9
Same as above
Scan #10 -- #29 are Modes 10--29, respectively
No issues other than those noted above.
Probably not the best source to have used frequency switching with.
Only testing Modes 1, 4, 7, 10, 15, 20, 22, and 29. Using 2 minute on/off pairs.
Scans #30/31 are Mode 1
Difficult to see the line
Scans #32/33 are Mode 4
Can't see the line
Scans #34/35 are Mode 7 * Abort on Scan #34. Restarted SB but aborted again on Scan #35. Cycled VEGAS off/on and resubmitted.
Scans #36/37 are Mode 7
Can't see the line
Scans #38/39 are Mode 10
Can't see the line
Scans #40/41 are Mode 15
VEGAS aborted during Scan #40. Cycled off/on and resubmitted.
Stopped SB during resubmit.
Argh. I had Offset("Encoder", 0.0, 0.0) for my offset. No wonder I couldn't see the line. Was left over from tests without motion.
Edited SB and resubmitted starting with Mode 1. Reduced time to 60 seconds.
Scan #42/43 is Mode 1
Not seeing data.
Seem to be having some VEGAS problems. Aborts and Banks not coming back up properly.
Cycled VEGAS off/on. Trying Mode 1 again.
Scans #45/46 are Mode 1
Data OK
Scans #47/48 are Mode 4
Abort in scan #47
Had to restart turtle, manually stop/start Bank C
Had trouble reconnecting in Astrid. Finally get things going again with 7 minutes left.
Scans #48/49 are Mode 4
Good detection this time
Scans #50/51 are Mode 7
Good detection
Had to stop due to end of session.
Session ends at 08:00
Conclusions
FSW scans ran well but this was perhaps not the best source and set up to use. But I think it will still be good enough.
We ran into lots of VEGAS aborts due to invalid data while doing the TP scans, as well as some Astrid issues. It would be good to get some more data in modes 10, 15, 20, 22, and 29.
