In the text discussing Tim's decreasing function for euclidean distance, the formula is displayed as: <img width="182" alt="Screen Shot 2021-01-18 at 8 34 53 PM" src="https://user-images.githubusercontent.com/6923376/104977070-a583a280-59cc-11eb-9af0-3924d4fd475f.png"> This shows the minimum of the Euclidean distance and some value. -- In the code (here shown as the PyMC3 version), the `T.maximum` is used: ``` def f_distance(gxy_pos, halo_pos, c): return T.maximum(euclidean_distance(gxy_pos, halo_pos), c)[:, None] ``` Shouldn't these two be the same? Thanks!
