Ecliptic longitude from Sun = -10.357° at true midnight ie at 23:56:40local civil
time April 22 Julian 967 AD
(Meridian of Phnom Bok)
OBSERVER(1) : intersection of the meridian of the PHNOM BAKHENG summit with southern
enclosure of Royal Palace (13.444754° N ; 103.855927° E) at 9 kam to the south of
Phnom Dei, 3 KY to the north of Bakheng summit, 17 KY to the west of Bakong and 16
KY to the north of the same temple ie on a 22 / 04 solar apsides line drawn from
the latter ( arctang(16/17) = 43.264° ; error = 0.0087°)
Radius (Rd) = 2.84253 km = 3.77766 KY
Az. = 0.127°
Runs through the centre of the central sanctuary of the Takeo temple
Radius = quarter of perimeter of takeo’s external enclosure.
(Glaize: The external enclosure wall forms a rectangle of 120 metres by 100)
The centre of the epicycle is located:
- on the central sanctuary of the Takeo temple.
- on the loxodrome between theAngkor Watobserverand the Krol Ko temple. This
loxod. is perpendicular to the loxod. from Thommanon to Takeo.
The parallel of Phimeanakas and the loxod. from Sun equant to Sun are tangent to
Radius (Rs)= 1.04234 km
= 1.38525 KY
The loxodrome from Ta Prohm to Krol Ko is tangent to the epicycle
The parallel of Victory Gate determines a Sighra ratio with respect to the centres
of Thommanon and Chau Say temples.
The Chau Say temple has dimensions related to the Sighra ratio:
57.5 / 157 = 0.36624
with 157 m = 5 kas = perimeter of enclosure (median axis) and 57.5 m = diagonal of
enclosure (outer corners)
Azimuth indicated by the loxodrome from the Mercury’s observer to the Linga of the
Error = 0.1°
The circumference C of the Linga is 3.77 m.
The perimeter P of the platform is equal to 48 m
C / P = 0.07854
Now, the eccentricity "2e" (equant) of Mercury is 0.0778
The planet is located on the axis of the Ta Prohm temple.
