Hey @xuanxu! Would love to review but I'm drowning in stuff to do right now. If for some weird reason you don't find anyone by mid-September, I could take this....

Hi @ThomasGWilson, I'll have to look at this to see what is going on, but in the meantime if it is a simple linear model, perhaps you can evaluate it...

Hi @jkteske, This has been an idea all along, but still not time to work on this. @dianadianadiana I think was working on this at some point, but I don't...

Hi Mohammad, Not yet, but I've thought of implementing this though. Should be very similar (and easier than) the TTV implementation. N.

Hi @radicamc, Thanks for opening this issue! I see your point, and I think you are right --- at least a warning should be raised indeed based on the support...

Hi @MohammadEftekhar, Sorry for getting so late to this. This is not allowed currently, but it's on my to-do's (it is useful for transit spectroscopy, for instance). Thanks! Néstor

Hi @JohannesBuchner --- good call on this one. If the model is a `global` model (meaning, you are fitting for a common realization of a GP on different datasets), then...

Yeah, but I remember that only worked if you had only _one_ sigma, whereas in the case of different instruments, you usually have a different sigma for each instrument. Because...

Yeah, in that case, the white-noise George solution should work. I should then create an if-statement for one-RV-instrument cases where this lazy evaluation is performed.

Hi @icweaver, Sorry for coming so late to this. I agree; `astropy` should handle these! Will update that on the next version. N.
