Computing the sundial

When you have entered all the data, launch the computation by pressing the Calculate button of the input box or typing Ctrl + M.

Calcad then calculates the sundial parameters and displays the graphical layout in the main window, and the details in the text window. These include an accuracy indication, at the beginning of the large text window:
o   If the accuracy indication is between 0 and 1, the sundial will be very accurate
o   If the accuracy indication is between 1 and 4, the sundial will be fairly accurate
o   If the accuracy indication is greater than 4, the sundial will not be accurate enough to be useful. Verify all the previous stages. Displaying the 2 shadow points by the Other menu may help you to find any input errors.
