[Rivet] aidamerge

[Hannes Jung]

Hi Daniel

thanks a lot..... I guess this should work.... I just don't know where to change what...
could you perhaps tell me a bit more what to change in which line, or perhaps upload the patched version somewhere ?

Thanks very much
cheers

Dear Hannes,

Dear Riveties

adding several aida files works fine, only in some cases I get the error:

Traceback (most recent call last):
 File "./aidamerge", line 65, in <module>
   sum_err2 += h.getBin(i).getErr()**2
OverflowError: (34, 'Numerical result out of range')

I guess it comes when a histo is not properly filled (fro example when a ratio is taken).
Is there a way to prevent these error message, and to continue with the program ?

I added a patch to catch the exception, use float('inf') during summing up and in the write out step this 'inf' is converted to a vee..eery large float.
Does this work for you?

@others: Is this the way it should work - or should we somehow exclude such bins?!?

Cheers,
Daniel
