Nick: Data_180711_8X.ovr
Plot Units: Mhz
Baseline: WIndow 0, Noise 1 is OK
Also try: (slow!) Window 5000, Noise 1
For peak finding, try Noise Mult 2.0
Use Delete and measure at each end
Unit MHz, Microwave
B = 1342 (float)
Zoom in: 13160-13540
T=2
I = 5/2
eQq0 = 500 (just to see width) (float)
Click on 5 most intense lines
Select first 2
Window = 100
Accept = 0.1 (Default)
AgI1.pgo
Search: 729 trials; First one OK (others rubbish)
Fit - look good
Transitions Window: "Replace"
Discard, "Low Intensity"
Discard, "Outside line list range"
Select all
Window 0.1
Search
Fit, floating D as well
All, Update
Assigns additional 8
Use lots of zoom, Show and Edit probably spurious assignment
- remove by clearing "Std Dev"
AgI2.pgo
Clear unset and Save to file AgI1.obs in (say) simple format.
Zoom 7750-8300
Float B only
Click on three most intense lines
Select first 1
Window = 200
AgI3.pgo
Search - two good fits corresponding to two isotopes
Cycle as above
AgI4.pgo, AgI2.obs
Need C sensible, so try C=15000 (Must be small enough to give K=1
population; exact value not important.)
Now pick a few strong K=1 lines; Use trial and error or
transitions window.
Now select all the assigned lines so far, and one K=1 line
Fix eQq, float DJK
CF3I3.pgo
One good fit;
Fit again including eQqComplete fit using transitions window, but
using "Discard, Outside plot range"
Narrow window to 0.1
CF3I4.pgo
Clear unset; shift window to 11800-12500
Click on strongest line
Float DJ
CF3I5.pgo
Search - may need to widen window
Add lines for this J and fit
CF3I6.pgo
Repeat for 15100-15450 region
This reveals peak finding issue for peak at 15253.6; use Show and
edit from residuals window, and manually measure peak from
original overlay.
Also float Cperp
