How do I find the number of 5th harmonic aspects (or any other harmonic for that matter) that a group of charts have?

Select the option Phases and Aspects in the research main menu. You will notice that you will have two division types: Phase or Aspect. Click on Aspect. You will notice that to the lower left there are boxes for you to change the orb you want to use as well as the harmonic that you want to examine. Once you have selected that, select the planets and points that you want to include in your scan. Run the program. You will get a bar graph showing the
results for the first two planets that you selected. Scroll down to the bottom of the drop-down menu for the points to be displayed and select All Points. This summaries your results. For example, for the actors, all 399 of them, I scan them for 5th harmonic aspects using an orb of 3 degrees. I found the following:

206 have conjunctions
145 Quintiles (72 degrees)
90 BiQuintiles (144)
111 BiQuintile (216)
138 Quintile (288)

Notice it will separate the 72 from the 288. To find which charts have a particular aspect, e.g., which charts have the 72 degree quintile, display the information in a table rather then in a bar graph. Then use the filtering tool to select that section of the table. Jigsaw will then place all of those charts into a separate file.
