AA+ v1.36

March 28, 2009

Just to let everyone know that v1.36 of AA+ has been released. Updates for this version include:

  • Fixed a bug in CAARiseTransitSet::Rise where the cyclical nature of a RA value was not taken into account during the interpolation. In fact Meeus in the book even refers to this issue as "Important remarks, 2." on page 30 of the second edition. Basically when interpolating RA, we need to be careful that the 3 values are consistent with respect to each other when any one of them wraps around from 23H 59M 59S around to 0H 0M 0S. In this case, the RA has increased by 0H 0M 1S of RA instead of decreasing by 23H 59M 59S. Thanks to Corky Corcoran and Danny Flippo for both reporting this issue.
  • Fixed a bug in the calculation of the parameter "H" in CAARiseTransitSet::Rise when calculating the local hour angle of the body for the time of transit.
