Legend
FEATURE
is a primary contact, a lunar crater or other feature timed.
TYPE is
the timing type, the four primaries as First Contact, Second Contact, Third
contact OR Fourth contact, OR MID as a MID-crater timing,
TIME of
the observation in hours.minutes seconds (eg 12.3645) in Universal Time.
Rc is the
computed radius of the umbral shadow at contact from the umbral centre in units
of the earth's equatorial radius.
Ro is the
observed radius of the umbral shadow at contact from the umbral centre in units
of the earth's equatorial radius.
Ro - Rc
is the difference in the two radii in units of the earth's equatorial radius
E% is the
computed enlargement of the umbra ((Ro-Rc)/Rc) X 100%, should be near to 2.0%,
if the result is greater than 4% it is rejected by the analysis program.
PSI is
the position angle of the timed feature on the umbra, from North through East in
decimal degrees.
X is the
computed x-coordinate of the contact point of the timed feature from the centre
of the Moon in decimal degrees.
Y is the
computed y-coordinate of the contact point of the timed feature from the centre
of the Moon in decimal degrees.
R is the
computed radius of the contact point of the timed feature from the centre of the
Moon in units of the Moon's semi-diameter (at primary contacts R = 1).
