problem quickCurve

[astrolog1986]

Dear Sir,

Using quickCurve from LATAnalysisScripts it calculates for several bins then
it returns this error:
<<
File "/opt/Fermi/x86_64-unknown-linux-gnu-libc2.5/bin/quickCurve", line 5, in
quickCurve.cli()

r = _zeros._brentq(f,a,b,xtol,maxiter,args,full_output,disp)
ValueError: f(a) and f(b) must have different signs>>

Can you please kindly help to solve this problem ?

Thank you!

Hi,

This is an error that another user was reporting and I couldn't figure out why it was happening. To help me debug it, can you post your config file as well as the XML model file you're using to generate the light curve?

Thanks,

Jeremy

Hi Jeremy,

Thank you for your answer!
Below is the config file which I am using. Unfortunately I am not able to
attach xml file to this text and send it. How do you want I sent to you ?

Thank you in advance!
