Solar Fire is shipped to you with the most commonly used chart options already selected for you. Choices like house system, coordinate system and zodiac are easy to find, as they appear on the “New Chart Data Entry” dialog itself. If you are new to astrology or Solar Fire then the options set when Solar Fire shipped should initially be perfectly adequate for your needs.
However, there are some less frequently used options that can be set in the “Preferences” dialog of Solar Fire, and you may like to set them before you start calculating charts.
•Geocentric Latitude Correction
•Lunar Parallax Correction
•Lunar Node Type
•Zodiac
•Angle Progressions
•Progression Day Type
•User Progression Rate
•Primary Direction Rate
•Vulcan Calculation
•Part of Fortune
These options are described in detail in Changing Preferences.
