Watney Solver v1.2.3

Improvements to large field solving

This version fixes issues when solving large fields with massive amounts of stars.

Related Watney Desktop release: https://github.com/Jusas/WatneyAstrometry/releases/tag/desktop-v1.0.3

Changelog

Changed

• WatneyAstrometry.Core updated to v1.2.3 which introduces improved match filtering. This mainly affects images with large field radiuses and massive amounts of stars visible, improving the solve accuracy. Fields with tens of thousands of stars should now solve with better accuracy.

Bleeding edge CLI builds

This release lists "bleeding edge" builds for the Watney CLI solver app, which are automated builds generated whenever new code is pushed to the master branch.

The watney-solve-bleeding-latest* packages are always the latest build. Older builds may be kept around for some time.

Ignore the source code. It is not the latest.

Watney Solver (API ONLY) v1.2.1

Bugfix release for Watney API

Fixes a bug that only affected Watney API 1.2.0.

Changelog

Fixed

• In API: When the API config file config.yml does not have limitThreads set at all, the API app will no longer crash on startup. This crash happened if you were upgrading from v1.1.3 to v1.2.0 and you were still using your old configuration, the reason being that the default limitThreads value was incorrectly being set to 0 instead of -1.

Watney Solver v1.2.0

Small feature and bugfix release

This version introduces solver thread limiting and fixes a logging issue.

Changelog

Added

• In the library: The solver now allows limiting the number of threads it uses. The new SolverGlobalConfiguration class allows setting a property MaxThreads that is respected by the Solver class. Example:

var globalSolverConfiguration = Solver.SolverGlobalConfiguration;
globalSolverConfiguration.MaxThreads = Environment.ProcessorCount - 1; // Default is Environment.ProcessorCount
Solver.SetGlobalConfiguration(globalSolverConfiguration); // After this the change takes effect.

• In CLI: optional parameter to allow limiting how many threads the solver can use. If the host is running other processes as well, it can be useful to limit the number of threads that is allowed to be used by the solver. By default when the parameter is not given then no limit is applied, i.e. the used thread count will default to the number of your CPU logical cores.

  example usage:

  ./watney-solve --limit-threads 15 ...

And to override the default value (0 which means do not limit), in the watney-solve-config.yml you can add:

  defaultLimitThreads: <number>

• In API: Configuration option to allow limiting how many threads the solver can use. In config.yml:

  limitThreads: -1

By default the value is set to -1 which does not apply any limit, i.e. the used thread count will default to the number of your CPU logical cores.. If the host is running other processes as well, it can be useful to limit the number of threads that is allowed to be used by the solver.

Fixed

• In CLI: When logging to file with the --log-file parameter the file I/O was excessive, slowing down solves significantly since the verbose logging produces so much log. This has been fixed by significantly reducing the file writes and instead the logs are mostly kept in memory until they get flushed to disk.

Watney Solver v1.1.3

Bugfix release, v1.1.3

A small but important bugfix release.

Changelog

Fixed

• Fixed the issue of truncating the exponent when writing long decimal
  numbers with scientific notation to the solve result WCS FITS file headers.
  This affects you if you were reading coordinates and the CD matrix from the
  outputted solve result WCS file.
  Watney CLI JSON and TSV output was unaffected by this bug.
