LmapWin Overview

LmapWin simulate the Lunar eclipse from 13000BC to 16999AD.

The LmapWin Eclipse simulation software has the following main features.

1) Display of the Eclipse Map
The LmapWin calculates and draws the eclipse on the world map.
2) Display of the Local Circumstance
The LmapWin calculate the local circumstance such as maximum magnitude,
time , altitude of the moon and direction at the given place.
3) Display of the Sky at Max. Magnitude
The LmapWin display the Sky view at maximum magnitude if that point is in
the area of the total eclipse.

(The above figure is Japanese version)

The improved point of Version 2.60 from Version 2.61

1) Consideration of the position of the center of gravity of the moon
A correction of the ecliptic longitude of the center of gravity
of the moon(-0.5") has been added to the Bessel elements.
(Contact time, etc. will change by about 0.5 seconds.)

2) The ƒĒT adjustment range has been changed from 10,000 sec. to 100,000 sec.
It is now possible to set Delta T to 0 seconds during Ancient Eclipses.

The LmapWin calculates based on the Bessel elements attached with the
software.The Bessel elements are for the eclipses from 13000BC to 16999AD.
