Hey! I am a new contributor and I recently discovered your project. Can I work on this issue?

[hornig]

@NamamiShanker sure, just start.
before you do a PR chat with us here https://aerospaceresearch.zulipchat.com/#narrow/stream/147024-OrbitDeterminator about it.

Hey if this issue is still open I will work on it. Could you give me a few example of cases?

Hey! I am new to open source contributions and want to contribute to this project. Can you please explain a little bit that what is the problem actually, with an example and what I have to do here to resolve that issue ?

[20JE0187]

What things and topics of orbit determination we should learn to understand the code and resolve the issue ?

Hey! I am new to open source contributions and want to contribute to this project. Can you explain what do you mean by 'selectable' here ?

I have observed that different values of mu of Earth are being used. For example ,
in this link https://github.com/aerospaceresearch/orbitdeterminator/blob/master/orbitdeterminator/kep_determination/gibbs_method.py#L15
, mu of earth used = 398600.4418 km^3/sec^2
and in this link
https://github.com/aerospaceresearch/orbitdeterminator/blob/master/orbitdeterminator/util/state_kep.py#L29
mu of earth used = 398600.4405 km^3/sec^2

So shall we go with any one value or with both values ?
