ÉCLIPSES

${\begin{alignedat}{3}t=&0^{h},\qquad &q=&-2636{,}97,\qquad &r=&+925{,}73,\\&1\;,&&-1497{,}36,&&+536{,}59,\\&2\;,&&-\ \,306{,}11,&&+154{,}36,\\&3\;,&&+\ \,964{,}70,&&-205{,}36,\\&4\;,&&+2337{,}44,&&-528{,}73.\end{alignedat}}$

On aura conséquemment

${\begin{alignedat}{2}q=&-2636{,}970\ \qquad &r=&+925{,}730\quad \ \\&+1124{,}484t\;\;\;&&-386{,}955t\;\;\;\\&+\quad \ \ 9{,}316t^{2}\,\ &&+\quad 5{,}152t^{2}\ \,\\&+\quad \ \ 6{,}041t^{3}\,\ &&+\quad 3{,}040t^{3}\ \,\\&-\quad \ \ 0{,}231t^{4}\,;&&-\quad 0{,}073t^{4}\,;\end{alignedat}}$

et de quart-d’heure en quart-d’heure,

${\begin{alignedat}{2}q=&-2636{,}970000\ \qquad &r=&+925{,}730000\quad \\&+281{,}121041t\;\;\;&&-\ \,96{,}738750t\,\ \ \\&+\quad 0{,}582266t^{2}\,\ &&-\quad 0{,}321979t^{2}\ \\&+\quad 0{,}094388t^{3}\,\ &&+\quad 0{,}047500t^{3}\ \\&-\quad 0{,}000902t^{4}\,;&&-\quad 0{,}000286t^{4}.\end{alignedat}}$

Donc
