MythicalBEAST

Release to support the Scylla HST project. Many improvements from multiple developers.
(not necessarily compatible with previous BEAST versions)

• fix bug in filter/vega files for HST bands
• improvements to AST generation
• improvements to simulated catalog generation
• improvements to splitting and merging for subgrids
• merging of stellar and dust prior code (support for megabeast dev)
• updates to batch file generation for large runs
• code restructuring to reduce complexity and duplication
• migrated to the new package template (APE17)
• moved from travis to github actions for CI
• moved from coveralls to codecov for test coverage reporting
• updates to testing structure and code
• various documentation updates and bugfixes

ProdtheBEAST

Current production version of the BEAST. Enhancements produced by a growing group of developers and users.

• adjustable stellar priors
• 2D pPDFs added
• improvements to AST generation
• AGB stellar atmosphere models
• tool scripts expanded and documented
• some scripts system callable (e.g., 'beast get_libfiles')
• examples moved to separate repository
• automated testing expanded
• various documentation updates and bugfixes

HerdtheBEAST

BEAST production version for a large herd of HST projects.

Changes:

• python 2 support dropped
• splitting run_beast.py up to be more pythonic
• AGB model atmospheres added
• generalized dust extinction curves (via dust_extinction package)
• can simulate observations based on physics/observation model
• observationmodel split by background or source density
• very simple splinter observationmodel added
• symlog used to support negative values in log pPDFs
• various documentation updates and bugfixes

UnleashTheBEAST

BEAST release for production runs for all the many HST observations in Milky Way, LMC, SMC, M31, M33, and galaxies beyond the Local Group.

Changes:

• systemic velocity of galaxy can be specified
• symlog used for flux pPDFs of with negative values
• ASTs can be based on source density or surface brightness
• model grid can be split up to allow parallel execution
  • resulting pPDFs can be reassembled
• various bugfixes

DistantBEAST

Changes:

• pip installable version
• library files in BEAST_PATH, ~/.beast, or in src directory beast/beast/libs
• automated regression testing
• distance added as 7th variable
• optimized generation of ASTs for toothpick model
• ASTs locations in observed images can be based on residual surface brightness image
• various bugfixes

FatBeast

Fully running version of the BEAST. Very close to the version for the v1 run on the PHAT data (45 million stars).
