Thanks @Serrof and @luc for discussing this interesting topic. I was actually looking to correct for annual and diurnal aberrations in Orekit (as far as I understand they still need to be corrected for when retrieving topocentric RA-Dec from the astrometric solution of telescope images). I didn’t find how to do it in Orekit, and, while I know how to correct for the annual aberration using other libraries or formulas, I cannot find reliable sources in general on how to correct for the diurnal one. Is there some way to do this in Orekit?
Regards,
