3d background elimination


I would like to do background elimination using TSpectrum3 class and subtract the back.
I cannot evaluate backgournd manipulating clipping window size.
Finally, I would like to perform peak integration after subtracting background.
Attachement file result.root includes hxyt_axyt 3d histogram. there are some peaks between 42000usec and 47000usec in z-axis.
Could you handle my data at first step?

Best Regards,

I forgot to attach my data root.tar.gz.
It is too large to upload the data.
So I utilized datadeliver free sites.

Below URL, you can download root.tar.gz.

datadeliver.net/receiver/fi … e2&lang=ja


download duration is expired.
I retried to upload root.tar.gz.
this includes hxyt_axyt 3d histogram.
I would like to subtract high level background.
using TSpectrum3 class.
could you handle my data?

you could download it at this site.

Sincery yours,


I cannot download your file, the web site is all in Japanese. Can you not upload the file on the Forum or upload in Dropbox. If you don;t have an account I can send you an invitation, but you need to send me first as private message your email address.

Best Regards


Lorenzo, try this link. (Parts of the contents will still be in Japanese, but there’s enough English to do what is needed.)
Check/mark “agree” then click the “blue button” below. On the next page, that will appear, click the “rootfile.tar.gz” link.

Thank you, I have downloaded the file.
I will look at your problem,

Best Regards


Thank you Lorenzo, Coyote.
I want to extract peak only from raw data, subtracting high level background.
I am looking forward to earlier response at your convenience.
Best Regards,
