Rectification Feature

[bspradling1]

Hi,

Is there any chance that Planetdance will have a rectification feature in the future?

If there is already a way to rectify a chart, can anyone give me tips on how to do that with the software?

Thanks so much in advance for your time.

Hi there - what sort of features would be helpful to you in rectification. It's currently possible to adjust any birth chart by hour, minute and second. This is very easy to do using the up/down buttons in the Toolbar. To set this up go to Options-Settings-General-Toolbar.

Hi Ed,

I was looking more at tabulating dates for significant life events, then possibly having it compute important degrees that may correspond with the angles.

Then I would be able to test them out with the other features in the program like solar arcs, progressions, and transits. If I can find a time that correlates with a birth time or at least particular rising sign that would be amazing!

Hi Brandi - thanks for getting back to us. A few questions:

How many dates would you need to look at?
Would it be necessary to enter a location for each date, or could you use the birthplace?

It should be quite easy to calculate the planetary positions at noon for a range of dates and display these in a way that would make the information easy to interpret. I'm quite busy at the moment but I'll give it some thought.

Thanks Ed,

For rectification, I think anywhere from 7-10 events give the most accurate data. Ten is optimal.

I don't think locations are as important. It can be based on natal location or ephemeris positions.

I appreciate your consideration! Thanks for making such amazing, accessible software.

Cheers,
Brandi

Thanks Brandi - this makes the coding relatively simple. I will give this some further thought and get back to you with some ideas. If you have any suggestions in the meantime add them to the thread.

All the best. Ed

Thank you so much!

Hi,
There is a rectification module at horoscope - extra - correction. You can maintain a database with events and have progressions, transits etc. The method is from W. van Dam, who also invented the van Dam primary progression.

Thanks Jean - there's so much in Planetdance I didn't realise what this module was for!

Hi Brandi - see how you get on with this module. I've never used it myself, but it seems like you create a database with the event charts, and then use these to vary the birthtime in the natal chart.

All the best. Ed

The dutch help was more comprehensive, here's a translation.
---------------------------
The idea is that you create a database with events so you can compare these by means of progressions / transit to a radix.
Using the big buttons you can change the time for the radix one minute forward or backwards.

Use Database to create or use other databases. Standard is 'correction.db'. 
Use Add to add events to the database so you can compare those times to a radix.
Use Delete / Change to delete or change these events.

Birth time correction.

The best result to correct a horoscope according to Wim van Dam - writer of the book 'Correction of the birth chart' - by releasing primary cuspen in combination with secondary planets and transits on the radixhoroscope on the day of the event.
It must be concrete events, whereby the (PR.) ASC or (PR.) MC must receive one or more aspects.
If the birth time is correct, these aspects will fall within 1 degree.
If the orb is greater and also occurs with other events, then click on the black arrows at the bottom right to adjust the birth time.

Start:
Click on the frame at the top right of the circle on Transit.
Then look at the aspects with the Radix.
Click Wheels / Aspect to view the size of the orb.
Then click SEC / Prim.
In the left column you now see the SEC. Planets with the pr. Cuspens.
Pay particular attention to the aspects of PR. ASC. and pr. Mc. (The 2 last columns) on the Radix and to aspects of SECPlanets on the R.Asc and MC.
Then look at their orbs by clicking on Wheels / Aspect again.

This analysis gives an accuracy of up to 1 degree of the MC, i.e. a birth time to approximately 4 minutes accurately.
One degree shift from the MC stands for approximately 1 year. (This can make a big difference with for instance Tr.Pluto at predictions)

N.B. Please note that the half squares (45 degrees) and one and a half squares (135 degrees) should be included, because they often play a big role according to Van Dam.

For an even more refinement of the birth time, Van Dam advises use annual harmonies. (Read his aforementioned book for this).

For information: According to Van Dam, as opposed to the primary cusps, the primary planets are a dangerous area and secondairy cups move much too quickly to be useful when correcting.
This was published in 1984, the opinion could be changed by now.

Thanks Jean I will give that a try!  I started adding events to it the other day before I saw your post, but didn’t know what to do after that.

I also tried the Trutine of Hermes, but it came out differently than when I did it by hand. And it was showing me charts on the right side that were from the 60’s and 70’s, but I was born in 1985. I was so confused 🤕

[Jean]

Hm that does not seem to be a very valid correction. That module was never really put to the test, you are the first to give an opinion.

Hi Brandi - I decided to take up the challenge of coding a rectification module. This uses ten transit charts (enter dates on the left), and then +/- hours or minutes. Calculate the rectified chart when you are done.

See screenshot of beta below.

Looks nice. But Ed we have to take care of feature bloat. It's getting out of hand.
If you ask me, i'd have the request for a fullscreen Ed greek as that will surely please a lot of people.
