READING:

Read the Sessions 1 and 2 of Hogg and Foreman-Mackey 2017.

Remember to include a README.md, in markdown format, that states how your team worked: who you worked with and what you contributed specifically. Remember captions!!

1. Uncerainties and Dark Matter

follow the instructions in the notebook MWrotCurve_instructions.ipynb. You are reproducing the work in https://academic.oup.com/pasj/article/67/4/75/1536635. The goal is to assess whether different treatment of uncertainties leads to different conclusions about the presence of dark matter in a galaxy based on the rotational curves of the stars within

rotational curves

The uncertainties in the original paper are treated as described in this paragraph description of assumption on the uncertainties

2. 661 students (and extra credit for 461)

Problem on MCMC and estimation of uncertainties (TBD)

Problem 2 in Hogg and Foreman-Mackey 2017. Most of the stuff you need to do it is in the Pi lab we did in class (e.g. the "isin" function is the same scheme you will use to reject proposals)
