Fitting failed in Xray calibration

[pohsun]

Hi,
I got a strange fit result and there's no obvious clue in the plot (Xray/q_Sn_C12_V0). Could you help me checking how this happens? The output root file is put in lxplus:~pchen/public/psi46/MoReWeb/issue108/pxar_Sn.root.

Thanks,
Po-Hsun

Hi Po-Hsun,

this seems to be the same problem than #80 , try setting

SpectrumFitImproveInitialGuess: True
SpectrumFitAdditionalConstraints: True

in global.cfg https://github.com/psi46/MoReWeb/blob/master/Analyse/Configuration/Software/global.cfg#L21

can I close this issue or does the problem still exists?

Hi,
I have checked the fit result with the new setting. The problem is indeed fixed!! However, this is only for our local part. The result on DB [1] is still the same...

Hi,
thanks for the feedback, results in DB will be reprocessed soon, but I don't know when exactly and it will take some time to process all modules :-)

OK, I see. Thank you!!
