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).
