What kind of transformation model is stellarium using for transforming form ICRF to planet surface(Earth, Mars)?

Asked by Christian Große on 2017-01-05

Hello Expert,

I will using Stellarium as a reference Simulator form my self-developed transformation algorithm which transforms from ICRF (or HCRF) to either earth or mars planet surface in my Masterstesis . Therefore I need a more or less detailed Information to which I can refer to.

Thank you for you help.

PS: I need it as soon as possible. :)

I need some informations for example:

For earth:
- Stellarium uses the transformation model IAU_76/FK5, IAU_2000/CIP based and so on.

For mars:
-Stellarium uses the transformation model from Folkner/Konopliv/Reasonberg and so on.

1) Do not use Stellarium as reference solution. We have a mix of many systems, some of which predate ICRF, and modernizing slowly. Some parts are not perfect, some model sources are still unidentified. See release info for progress.

Download the source and check for yourself. If you find a bug or can identify some undocumented algorithms, please solve and submit patch! See the manual for references.

2) For new work, start with the Explanatory Supplement to the Astronomical Almanac, 3rd edition, 2013.

Can you help with this problem?
