Chart Calculation and Storage
Contents
When the Solar Fire program saves and reads charts to and from chart databases, only the chart details are stored e.g. name, date, time, location, etc. Planetary positions and house cusp positions are not stored in a chart database file.
However, once a new chart is cast in the program or opened from a chart database, all planetary positions and house cusps are calculated and stored until the user exits from the program. These are known as "Calculated Charts", and the Main Screen displays a list of all such charts in a list box.
It is only possible to display a chart, aspect grid, report, or to generate any subsidiary charts, after that chart has been calculated and is listed in the "Calculated Charts" list box on the Main Screen.
Calculated charts can be of any type - natal, progressed, return, composite, harmonic, etc.
The following table summarizes which chart types may be used in each type of operation. The R symbol denotes that it is possible to perform the operation in the left hand column on the chart type at the top of that column.
The chart operations are as follows.
Open |
To retrieve chart details from a chart file and calculate the chart |
Save |
To store the details of a chart to a chart database file |
Edit |
To copy and edit an existing calculated chart |
Delete |
To delete a chart from the list of "Calculated Charts" |
Retain |
To retain calculated charts for use in future sessions |
Progress |
To calculate a progressed or directed chart from a base chart |
Return |
To calculate a planet or asteroid return chart from a base chart |
Combine |
To calculate a combined chart from two or more base charts |
Harmonic |
To calculate an harmonic or arc transform chart from a base chart |
Antiscia |
To calculate an antiscia or contra-antiscia chart from a base chart |
Locality |
To calculate a relocated or locality chart from a base chart |
View |
To view a calculated chart or aspect grid on the screen or to print it |
Report |
To generate a report from a base chart |
Dynamic |
To generate a transits/progressions report or graphic ephemeris from a base chart |
Charts which are equivalent to Natal are - Return, Ingress, Transit, Davison, Lunar Phase, Lunar Phase Return, Rise/Set, Prenatal, Relocated
