AA+ v1.73

October 16, 2016

Just to let everyone know that v1.73 of AA+ has been released. Updates for this version include:

  • Improved the accuracy of CAASun::ApparentEclipticLongitude when the bHighPrecision parameter is true. The code now uses a new VariationGeometricEclipticLongitude method which provides a new higher precision method to calculate the effect of aberration. This takes into account that Earth’s orbit around the Sun is not a purely unperturbed elliptical orbit. This improves the accuracy of the sample 25.a/b from the book by a couple of hundreds of arc seconds. The results now are exactly in sync with the results as reported in the book. Thanks to "Pavel" for reporting this issue.
