AA+ v1.93

March 2, 2018

Just to let everyone know that v1.93 of AA+ has been released. Updates for this version include:

  • Fixed a transcription bug in the CAAPrecession::PrecessEquatorial method. The "0.017998*tcubed" term was incorrectly using "0.017988*tcubed" when calculating "sigma". Thanks to Michael McLaughlin for reporting this bug. The errors were so small that the values from the worked example of 21.b from the book ended up giving the same results. If a longer timespan was used for the example instead of the 28 years then the errors would have been easier to spot from the incorrect terms. Hopefully this is the same transcription error in this method!
