Astronomical commissioning observations for all LBW modes.
All data will be taken on J1713+0437
Calibration and fold scans will be taken for all appropriate modes.
Search mode scans will be taken in all modes.
GUPPI will be used simultaneously as appropriate.
All science scans will be 900 seconds.
Session begins at 01:45. Joe starts switching to test VEGAS version.
Joe finished switching versions at 02:00
Scheduling block submitted at 02:01
First scan number is #14.
Pulsar detected in i0100x0512, though there seems to be every so slightly more smearing than in the GUPPI data, and the off-pulse noise in the phase vs frequency domain doesn't seem Gaussian. Will need to investigate this further.
i0100x1024 still not looking right. This is the mode where the apparent folding period is off.
i0100x2048 scan seems to have failed. This was the new BOF file build
Stopped SB and commented out i0100x0512 through i0100x2048. Resubmitted at 03:48
Bandpass levels are all zero for i0100x4096 with vscale = 5000. Trying again with vscale = 10000.
Still no power with scale at 50000 and 64000. I don't recall a previous problem with this. But going to move on...
i0200x1024 looks good. Seems like good agreement with GUPPI data
VEGAS failed to activate on i0200x2048 scan. Trying again. Same thing.
i0200x4096 and i0200x8192 scans seemed to run OK
Running low on time. Will need to reduce coherent scan lenghts to 5 minutes.
c0100x0064 looks good
c0100x0128 looks good
c0100x0256 looks good
c0100x0512 looks OK in fold mode, though power levels may be a bit low. Lots of packet loss in search mode.
c0200x0064 seems OK
c0200x0128 seems OK
c0200x0256 seems OK
c0200x0512 seems OK
c0200x1024 seems OK. Significant packet loss in search mode.
Session ended at 07:57. Joe switched back to release branch.
Checkouts done at 08:35.
Need to look at pulse width and off-pulse noise in i0100x0512
i0100x1024 still not looking right.
Need to look at i0100 modes and i0200x2048. Other modes seemed mostly OK. Will analyze in detail later on.
