Full Changelog: v0.3.2...v0.3.3

v0.3.2 Fix Likelihood + data w/Cov Bug, more QOL

@tomasstolker saves us yet again. Major clarifications and improvements to the package structure (no more binary files, for instance). Fixed a big bug where data with covariance between terms was not included in the likelihood function (this was defeating the purpose of including all our excellent GRAVITY data!) and a few more knobs and user options (like setting sampling style within dynesty - if your sampler is running slowly, try changing the sample_method keyword from 'unif' to 'rwalk' or 'rslice' in system.fit !)

v0.3.1 pypi fully operational

A quick hot-fix to ensure that installing directly from pypi, e.g.

pip install backtracks

includes the data files needed to run. Now, no need to clone the repo! Just run

conda create python=3.9 -n backtrack
conda activate backtrack
conda install pip
pip install backtracks

download our example data and script (or make your own), and run

wget https://raw.githubusercontent.com/wbalmer/backtrack/main/tests/scorpions1b_orbitizelike.csv
wget https://raw.githubusercontent.com/wbalmer/backtrack/main/tests/hd131339a.py
python hd131339a.py

pypi installation released! and more QOL improvements

Some big PRs including wonderful updates from @tomasstolker , and now backtrack is officially bundled as a package install-able via

pip install -e .

or

pip install backtracks==0.3.0

Cluster ready!

Thanks to @tomasstolker , backtrack can now be used on clusters using schwimmbad.MPIPool

new also is the set_prior_attr function and new options in the fit function, like nlive=500, mpi_pool=False, resume=False.

More to come (maybe someday I'll write docstrings)!

Initial Release!

Hello world!

backtrack is here, and I'm version-ing the code here so we can continue development. Lots of work yet to be done (like docstrings, lol) but we can reproduce the results of Nielsen et al. 2017, and the code appears applicable to at least one other case (citation TBD), which was the intention of the code in the first place.
