lalapps_PredictFstat: make psi,Alpha,Delta optional?
@karl-wette since it's perfectly legal to use this code to estimate pure-noise 2F (trivial answer: 4) and h0,cosi,phi0 are already optional, I'm wondering why we don't do the same for the 3 remaining signal parameters.
Probably the original thinking in making them required was to guard users from thinking they're irrelevant and there's such a thing as the "true" predicted value for simply a (h0,cosi) pair without thinking about the other parameters; but to deal with that, we could still throw an error if h0>0 and any of the others are not set, like we already do with cosi.
Should be a straightforward MR, but I'd like to hear your opinion before doing it.
