How do I use JigSaw to find which members of my group are affected by a particular eclipse (or any fixed zodiac position)?

Select the Family Search option. In the main screen select "Specified Position", then enter in the degree of the eclipse. Select the harmonic; choose the orb and; select the natal points. Jigsaw will now scan the group and find which family or group members are receiving an aspect from the eclipse (or any other fixed position). Jigsaw will first find which natal point is receiving the aspect and then display which family or group member is involved.
