In fact much more than any button because it would be me entering the equations. There’s a programme for Windows called XPSpeak which allows me to fit semi-Voigt functions convolved Gaussian-Lorentzian lineshapes to experimental spectra, as well as doing background subtractions. I meant to alter the code to give you an interface. I also hope that the new features in this program can be adopted by the XPS manufacturers in the later versions of their software. O Incidentally the background fit I did was far from a simple linear fit. I just had a quick look at the Fitt programme you linked to in a previous post

Is that the case, Juggies? Or am I missing something here? The other problem I have with XPS data is I’m going xpspeak 41 be using some theoretical calculations some of my own, some in collaboration with Cambridge university of the valence band electron density-of-states to compare with experimental XPS data. I was just pointing out that absolutely anything, that can multiply and add, can do convolution. Kwok This version of the program was written in Visual Basic 6.

The Xpdpeak Laboratory XPS machine uses a high intensity, highly monochromated Xpspeaak K-alpha x-ray source, but other instrumental factors also contribute a Gaussian lineshape to the data. Just xpspdak a look at fityk and it does have an option to fit pseudo-Voigt functions to XPS data. Thanks again to everyone.

On a different note I came across this site which might be of help http: Some of xpspeak 41 links looks xpspeak 41, and I’ll see about getting the DLL, but that in itself seems rather kookie – XPSpeak works fine in Windows without any issues.


I know that all the CCP work were free but I think many of their work are vanishing It xpspeak 41 impressive but like I said I used numerical recipe code for all the hard stuff. Flinn for the routine of reading Leybold ascii format, Prof.

If it doesn’t, I’ll xpxpeak going down the VM route. Xpspeakk you fitting by hand? One more thing I forgot You simply coded the equation you wanted to fit, the range to fit over, some parameter estimates and it did non linear fitting. As far as using pseudo-Voigt function for xps;eak fitting thats a bit odd unless ofcourse you are using non-monochromatic x-ray. Not sure if it will give me the freedom to manually fit peaks that XPSpeak gives me.

X-ray Photoelectron Spectroscopy: XPSpeak [Archive] – Ubuntu Forums

You may all be pleased to know that I have actually got to know Crossover and have xpspeak 41 that to install working copies of both Origin and XPSpeak. Thank you to all who have replied since my last message.

As such, you invariably have to accept that no matter how good the source, the data will always have Lorentzian from the lifetimes of excited states and Gaussian components. I’m a condensed matter research physicist and xpspeak 41 x-ray photoelectron spectroscopy XPS a fair amount. I was doing X-ray spectroscopy at the time.

I can’t think of any subtle effects that are outside this method but let me know if I am wrong.


Xpspeak 41 social advice

If Winamp xpspeak 41 supposed to work in Wine then it surely means I’m doing something wrong and should have a look at it again more closely. X-fit was developed xpspeqk the CCP project: DLL from Microsoft here http: Does anyone have any suggestions how to do that?

As for fityk, I’ll give it a shot.

I would totally trust xpspexk to do convolution. To be honest though, I’m still quite new when it comes to Linux and Wine does confuse me a little. The background in XPS data isn’t as simple xpspeak 41 a linear background either, but is a slightly more complicated “Shirley” background, although if Kwok can implement that then it shouldn’t be too much of an issue. I also did try to get hold of Kowk at Hong Kong University, xpspeak 41 his e-mail address wasn’t working.

In order to do this I will need to convolve the calculated data with Gaussians and Lorentzians. There is an excellent peak fitting program in the repositories: What I could do with though is a graphical interface when fitting the data xpspeak 41 there are many subtle effects that influence the shape of XPS features which are impossible to code into an automatic fitting program and necessitates a trial and xpspeaj approach by hand.
