. 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.

In this method the fields outside and inside a particle are represented by expansions in term of proper basis functions (practically always the vector spherical harmonics). Since the particle surface does not coincide with the coordinate surface, it is impossible to satisfy the boundary conditions exactly, and the expansions are limited by a finite number of terms, and the boundary conditions are considered in a finite set of points (matching points). ...

... These values are functions of the geographical (geodesic) latitude and the height of the point above the sea level. ... The option also permits to solve the reverse problem — to calculate approximate values of observatory latitude and its height above the sea level depending on the introduced values of dxy and dz. ... It should be mentioned that low precision of dxy and dz for some observatories in the list maintained by MPC leads to negative value of height above the sea level for some of them. ...
