In this astronomical chart (front and back) Gibbes provides on the front page a diagram and the elements for constructing the diagram. Those elements are hourly motion, declination, hourly motion in declination, horizontal parallax and semidiameter. Gibbes also provides the result times of the eclipse including the beginning, total, opposition, middle, end of total, general and duration of eclipse. On the back of the page Gibbes provides his calculations for the result times.
