    RE: g36659 and g36654

    Dear Paul,

    Thank you very much again for your very in-depth comparison analysis between our results. It brings new elements since I was not aware of the slight differences between our DeltaT values.

    But first of all, one more question to fully clarify this point: do you apply in your Lunar Software the Moon correction which I am using and to which I refered under the following terms in http://fer3.com/arc/m2.aspx/Modern-Lunars-Couëtte-sep-2016-g36570 :

    QUOTE - For the Moon, corrections of Δλ = +0.50” and Δβ = -0.25” have been added to the Mean Ecliptic of Date Coordinates to approximately account for correction from Center of Mass (from INPOP13C) to Center of Figure. Such corrections translate here into: Δα = +0.478” and Δδ = -0.351”.  UNQUOTE


    Thank you very much for your Kind Attention and for your Reply,

    Best Friendly Lunarian Regards,
