A Harmonic Aspect Grid of an individual chart and a Harmonic Aspect Grid between 2 charts can be produced in earlier versions of Sirius. Now you can select the highest harmonic and the orb of the first harmonic, from which the orb of other harmonics is proportionately based. This new flexibility allows astrologers interested in harmonics to select the range of harmonics that are of interest and to select the allowable orb in these aspect tables.
