Main Tab - Show Heliacal phenomena
When this checkbox is checked, the heliacal phenomena will be shown in the graph. What happens is as the graph is drawing, it checks the relationship to the Sun and when the planet is within 15 degrees it draws a small circle on the graph that indicates when it heliacally rises or sets and hovering over these dots will give the heliacal phenomena. If unchecked, the line will be constant with no breaks indicating position throughout.
The reason for showing heliacal phenomena is that in Hellenistic astrology, these are some of the phasis conditions (meaning an appearance that speaks) and these show intensification of the planets at that time. They are as important as line crossings indicating exact aspects (if not more so).
