ASCOM.AstrometryTools

Library of Astrometry components mirroring those in the ASCOM Platform.

Version History

The version history only contains entries when a change is made.

Release 3.0.0

  • BUG-FIX - Fixed bug where the NOVAS component gave incorrect answers on 32bit Windows platforms. Other platforms were unaffected.
  • ADDED - Support for .NET 8.0, 9.0 and 10.0 target frameworks. It will no longer be necessary for applications that use these frameworks to rely on the .NET Standard 2.0 component.
  • ADDED - Over 200 additional SOFA functions, now, all functions in the SOFA library are available.

Release 2.2.0

  • Add SetObserved() and SetAzimuthElevationObserved() methods to the Transform component.

Release 2.1.0

  • Improved NOVAS ra cio bin file handling to enable use when the file cannot be located and the internal mechanic is used.
  • Transform - Add observed mode to enable unrefracted topocentric coordinates to be converted to refracted topocentric coordinates i.e. observed coordinates.
  • Astrometry Tools can now be used in applications that run on Android 32bit and 64bit.

Release 2.1.0-rc.4

  • Improve NOVAS ra cio bin file handling.
  • Transform - Add observed mode to enable unrefracted topocentric coordinates to be converted to refracted topocentric coordinates i.e. observed coordinates.

Release 2.1.0-rc.3

  • Replace Android libraries for NOVAS and SOFA with differently compiled versions. Improve log messages.

Release 2.1.0-rc.2

  • NOVAS - Add additional search paths for the JPLEPH file to make it work on Android

Release 2.1.0-rc.1

  • Add experimental SOFA and NOVAS support for Android 32bit and 64bit.

Release 2.0.0

  • No change.

Release 2.0.0-rc.28

  • Native library calling convention for SOFA and NOVAS changed to CDecl in order to remove an "imbalanced stack" condition when calls return. The issue seems
  • to have been handled transparently in Release but was reported in Debug configurations.

Release 2.0.0-rc.23

  • Initial release after migration of features from the ASCOM.Tools package.
  • Significantly reduced package size by restricting NOVAS Planet ephemeris data to start at the year 2020 rather than 1900
  • Extended the range of NOVAS Planet ephemeris data to the year 2050 from 2035.
  • SOFA updated to Release 19 dated 11th October 2023.
  • Fix - AstroUtilities.JulianDateFromDateTime extended to handle dates more than 5 years in the future.
  • Fix - Removed very small error (6th decimal place) in AstroUtilities.JulianDate function
