The question of orb

OMNICYCLES allows you to prepare your graphs in numerous ways; as mentioned in other sections in this site, you may choose the combination of planets you wish to use, vary the orb, and also treat the orb in different ways. For example: normally, the number of points given to an aspect will be highest when that aspect is exact, and will then gradually decrease in proportion to the orb of the aspect; when the two planets involved are no longer within the orb allowed, no more points will be assigned to that aspect. Hereīs an example of what an OMNIGRAPH looks like when this type of orb-scheme is used:


  Example: Transit Pluto: the peaks represent exact aspects; the bigger the orb becomes, the more the line on the graph drops, in proportion to the orb.    
   Some astrologers, however, opine that when near exactness, the number of points should remain higher than in the above scheme, and then drop off more quickly at a later point.
OMNICYCLES lets you experiment with this, by using files which employ what we call (for the sake of convenience) the "special formula"; this is a variant of  the formula used for resonance frequency, as explained in Geoffrey Deanīs work "Recent Advances in Natal Astrology". (For those familiar with this book: We modified the formula which Dean gives somewhat, so that the number of points for an aspect would drop to zero when the aspect is out of orb; also, we generally replace the "3" in his formula with "20", though OMNICYCLES lets you replace this variable with any number you want). The following is the same Pluto-graph as above, BUT using the "special orb formula". (Please note: the fact that the peaks on this second graph donīt go as high as on the first has to do with the different "mean" values in each file, i.e., when the orb-formula - or any other value in a file - is changed, the "mean" must be recalculated for the new values. OMNICYCLES is delivered with more than 150 files for which these "mean" values have been pre-calculated for you.)
  Yet there is also another way to treat the "orb" question, which is much simpler than either of the two possibilities above. Letīs assume that the maximum number of points for a particular aspect is 128. In this scheme, the aspect will receive 128 points no matter what the orb: that is, as long as the two plantets are within the allowed orb for this aspect, the aspect will be assigned 128 points. This will give a graph which looks like this (using once again Pluto transits):    
  Here, it is plain that the same number of points is being given to the aspect for as long as the aspect lasts...    


Now, astrologically speaking, we donīt generally recommend this scheme, for it seems obvious that an exact aspect should have more of an effect than one which is almost at the limits of allowed orb. Nonetheless, we have included this possibility for certain types of astrological work. For example, perhaps you want to see at a glance exactly how long a certain aspect will be within orb; this type of graph shows it very clearly indeed. Using the "multigraph" function, you can also superimpose one type of graph upon another, as we have done in the following example. Here, we have two Pluto graphs together. The red/blue lines are the same as in the graph above, (in which the points donīt vary with orb); the ****** lines represent the first graph on this page. Here, it can be seen not only how long the Pluto aspects are in orb, but
ALSO how their strength waxes and wanes over time


  In addition to allowing you to treat the question of the aspect orbs in the ways described above, OMNICYCLES also offers you several ways to evaluate the manner in which simultaneous aspects are treated. This special feature will no doubt interest many astrologers. However, since it may seem a bit complex until you get to know it, we think it deserves a clear explanation, with graphs to illustrate.
