Description
In case in the input model XML file we have tscalc="1" to signal that TS should be computed, the following code returns a misleading result:
like = ctlike(input_obs) like.run() print(like.opt().value())
The
print statement will show the value of the latest optimisation. If the TS computation was enabled, this corresponds to the optimisation without the source of interest (also the other way round if TS was disabled the overall likelihood value is shown). The user might expect to retrieve the value of the overall fit in any case though.I am not sure if this is really a bug, or more a feature
Recurrence
No recurrence.

I agree that the value of the overall optimisation should be returned. We therefore should do the optimisations for the TS computation with a copy of the optimiser, not the optimiser of the ctlike class. So, ctlike::reoptimize_lm(void) should work with a clone of the optimizer.

Good idea. Fix is available on branch 1654-ctlike-likelihood-value.
