As the title states, are questions that ask for help with calculations, or help with the results of the said calculations, on-topic? or are they off-topic, and would have a better home on a site like Physics.SE, or Mathematics.SE, or elsewhere?
Some Specific Context:
I'm working on a little side-project relating to orbits and orbital positions of objects in our solar system. I am relatively new to the mathematics behind orbital mechanics, and my understanding goes as far as what I have read online (and a few hundred hours of Kerbal Space Program...).
I have managed to adapt what I have learnt into some code to calculate cartesian and spherical coordinates. However, when I have fact-checked the output against records on JPL's HORIZONS System some of the results are not what I am expecting to see.
So I would like to ask about my understanding and implementation of the calculations, and whether I am interpreting my results correctly.
Checking in the Help Center, I would say that this question probably falls under Planetary Science and Celestial mechanics, but there does not seem to be any pointer as to whether help with calculations is something that is accepted on this site.
I also had a quick search for Maths and Calculations here on Meta, and the only two questions that seem relevant (this one, and this one) do not answer the question.
