. Computer Ephemeris. Lunar eclipse numerical map. Explanations. First portion of the page contains coordinates of sub-lunar points during the eclipse. Every point is represented with two numbers: geodetic longitude and geodetic latitude, both in degrees. Second portion of the page contains coordinates of the points at terminator line for the moments of contacts. There are 360 points on the lines, tens of them per line. The starting angle is indicated in the leftmost column.
