So just post actual spectra below 300 keV ... as in Figures 1 and 2.
Figures 1 and 2 are a minuscule part of the actual spectra
. these screenshots yield nothing of value .
as has been pointed out in the text
"Here more than 300 lines are active - high above the background - at the “same” time and some are overlapping or pretty close. So only an inspection of the histogram file finally can tell the truth.
and multiple times in this thread//
BruceH is rather tedious
Display MoreThe reason I ask is because I have realized that the noise that must be part of Wyttenbach's background spectra accounts for the small wiggles I see in Figure 1 of the ResearchGate paper. Wiggles such as the ones I have drawn a box around , here ...
I don't believe that these are peaks corresponding to separate gamma lines because they go up and down much faster than is compatible with the physics of the NaI crystal in the detector Wyttenbach uses. Instead, I think that these wiggles represent Poisson noise in the background samples and appear here because of the subtraction process. They are about the right size for Poisson noise.
If the same background sample was used for background subtraction in both the spectra seen in Figure 1, it would explain why each and every such wiggle is replicated in both spectra. Whether or not the same background was used repeatedly when preparing these spectra is undocumented.
It would be interesting to know whether Wyttenbach is interpreting each and every wiggle here as a separate spectral line.
In a one-time averaged-background-subtracted spectra, the sharp dips are now the common background elements. U and Th decay chains, K, Rb, that sort of stuff.
Sometimes they were called “grapes”, after the colloquial name for dripping weld material.

a question about Dash's historic loading of natural uranium foils with H2
In the AtomEcology text is written
"
5.1
Higher Z nucleus syntheses
As our cold fusion experiments do show, potentially all elements of the periodic table can be produced by the basic reaction of adding H*-H* or D*-D* or H*/D* to a nucleus.
Dash produced some surprising preliminary results,which indicated nuclear reactions..
https://www.lenr-canr.org/acrobat/DashJchangesint.pdf
Could H*2 addition reactions have been operating to produce
Np237,Pu237 and
Np240,Pu240?
and the increase in the U235 Th234 keV lines be due to LENR downscaling?

I was planning on doing some experiments to see if the CPS could be influenced by various things.
Part if that was getting the counts out of the scintillometer in a reliable way. The sounds on the GR-110 are the actual counts, not a representative Hz.
(Well, not exactly anyways, I hope you get what I mean.)
The display is 7-segment LCD, and the input to that might be read. Can once had a video display reader program working quite well a while back.
Products I wouldn’t presume at all. Everything we did was NORM, although mighty strong in some cases. “Uranium” was Bi214, Ra, etc…Th
lead isotope ratios messed up
Geiger CPS?
a pretty blunt tool
Dash used an alpha beta counter plus a gamma spec..
You could try Xray film or a CD? they can't pick out Plutonium very well.

I always have my eye open for a spectrometer. They are getting scarce again.
Here is the GR-110 brochure.

Only excitation down scaling should (could) be seen. There are no magnetic moments that can react. But U235 has many decay paths also 234Th.
These elements are only of theoretical interest.
Do you intend to post examples of the actual spectra that you analyze in your ResearchGate mansucript? I am asking you for background and fueled spectra below 300 keV and containing the same values that you say you use to find lines.
mansucript?
manuscript?

Repetition is tedious Bruce..
Repetition is Hell! If Wyttenbach and Ecalox have sensitive data there must be a very good reason for that, so such omission of data should be respected amongst this scientific community. Personally I agree it should be published soon with total transparency!
If you will not post the data which you actually analyze in your manuscript, then I will press ahead using Figure 1 to illustrate my point. If you think that Figure 1 is unsuitable ... well then that is your fault, not mine.
Wyttenbach's manuscript purports to identify many spectral lines emanating from his fuel. He then uses these lines to back up his LENR theories. But the fundamental move here -- detection of multitudes of separate spectral lines -- is dubious. I have tabulated the lines* Wyttenbach claims to find in the 0-270 keV range and represented them as black lines beneath the 250C spectrum from Fig 1. There are more than 211 of them here.
I do not believe that Wyttenbach's system has the physical ability to resolve so many lines so close together. The resolution of the NaI detector he uses is an order of magnitude coarser than would be needed for such work. Also, his algorithms do not detect "peaks" -- they just find bins with more counts than he thinks should be there but without taking into account scattering or noise. Wyttenbach now needs to convince us that his procedures do not just generate hordes of false positives.

Electric cars at least are getting cheaper due to Elon Musk's new $5000 driverless model. Why not fit a BEC hot tube for the heating system in freezing cold weather?

I understand that for a dilettante it is frustrating just to see what others do and not to have access to the deep details. Only people we trust get the deep details. Your arguments are not worth discussing as you simply understand no basics.
May be once go to a lab and try to make your first measurement...
I am saying that the method you describe for specifically and accurately locating myriad spectral lines in a complex signal does not work even in principle. To counter this, you don't actually have to show any of your secret data. You could just create a surrogate dataset consisting of spectral lines at random energies (for example by convolving the set of lines with the empirically determined impulse response of your NaI detector), run it through your peak-finding algorithms, and see if you detect the lines with reasonable fidelity.
To counter this,
First show that you have understanding not just wiki-logy...
E.g. explains us which troubles you see with measuring a single photon within 50ms ...

oh gamma illiterate 
In a one-time averaged-background-subtracted spectra, the sharp dips are now the common background elements. U and Th decay chains, K, Rb, that sort of stuff.
I though this would be the case too. But here is the background spectrum Wyttenbach posted.
Remarkably smooth for a spectrum that has not been averaged! And the little wiggles that do appear here are no more than about 0.5 counts from peak to trough whereas the wiggles in the background spectra are about 4 times larger. So I don't think that this background account for features in the background-subtracted spectra.
Another thing I don't see in this background spectrum is the set of "most active discrete lines" that Wyttenbach describes in the text as 63.3, 92.4 and 92.8 keV. Wytttenbach has not provided a good explanation for this disappearance.
Sometimes they were called “grapes”, after the colloquial name for dripping weld material.
Are the features indicated by red lines examples of the sort of thing that you would identify as "grapes"? Or do you have something else in mind
?
