Samples are stored in a pymc3 trace file called aumicb_pymc3.tgz. The tile will need to be untarred first you can use tar -xzvf aumicb_pymc3.tgz<br><br>This is a custom data format for PyMC3 traces. Each chain goes inside a directory, and each directory contains a metadata json file, and a numpy compressed file.<br>File can be read using sample code supplied. The code is in a jupyter notebook called AU_Mic_read_samples.ipynb. The full file will need to be run because the samples rely on the model being set up correctly.<br>Several python packages are needed to run the notebook:<br>numpy, matplotlib, lightkurve, exoplanet, pymc3, theano, scipy, corner, pandas, and astropy<br><br><br><br>
