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, 1 C first
contact, 2
C second contact, 3 C Third contact OR 4 C Fourth contact (these last
four
contact timings refer to the umbral contact with the crater edges).
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).
