Example from the book “Astrologia Mundial”, by Juan Estadella.
As an example of the Barbault variant for the planetary concentration index, I will show the index corresponding to 0 hours on January 1, 1940.
In order to easily calculate the distances between the planets, we will convert the position in degrees and minutes of the planets in the signs, directly to a position in degrees, disregarding the minutes. In addition, we will measure them from the 0 ° of Aries. The result of the conversion is as follows:
Jupiter: Io (Io 09 ‘of Aries) Saturn: 24 ° (24 ° 26’ of Aries) Uranus: 48 ° (18 ° 16 ‘of Taurus) Neptune: 175 ° (25 ° 31’ of Virgo) Pinton: 122 ° (Leo’s 2nd 15 ‘)
From here, we must proceed, according to Barbault’s cyclical variant, to calculate the different angular distances between the slow planets:
Jupiter-Saturn: 23 °
Jupiter-Uranus: 47 °
Jupiter-Neptune: 174 °
Jupiter-Pluto: 121 °
Saturn-Uranus: 24 °
Saturn-Neptune: 151 °
Saturn-Pinton: 98 °
Uranus-Neptune: 127 °
Uranus-Pluto: 74 °
Neptune-Pluto: 53 °
Total: 892 °
According to this calculation, in which all the angular distances between the different planets are added together, we obtain a planetary concentration (cyclical) index of 892 °.
