When composing chart search conditions, "Midpoint" allows you to select...
•"First Midpoint" – consisting of 2 Planets, Points or Cusps (A and B) – any of Solar Fire’s standard chart points, or any of the 12 house cusps
•"Modulus" – any degree value available on the drop-down list, or any other value typed in by the user
•"Orb" – any degree value available on the drop-down list, or any other value typed in by the user
•"Second Midpoint" – consisting of 2 Planets, Points or Cusps (A and B) – any of Solar Fire’s standard chart points, or any of the 12 house cusps
Also, for Chart Searches only, whether the second midpoint's placement relates to...
•The same chart - i.e. the contact occurs between the two midpoints in the charts being searched (the selected radix chart is not used)
•The radix chart - i.e. the contact occurs from the first midpoint in the charts being searched to the second midpoint in the selected radix chart
or... for Electional Searches only, whether the second midpoint's placement relates to...
•The transiting chart - i.e. the contact occurs between the two transiting midpoints (the selected radix chart is not used)
•The radix chart - i.e. the contact occurs from the transiting first midpoint to the second midpoint in the selected radix chart
Example: Mon/Ven contacts Sun/Mer in 90° modulus within 1° orb;
Note: To specify a normal chart point instead of a midpoint, simply ensure that both the A and B points are the same point.
