This is the repository for paper "Broken into Pieces: ATLAS and Aliqa Uma as One Single Stream" (Li et al. 2020)

Radial velocities (RV) and metallicities of the member stars (i.e. Table 1 in the paper) and the distance moduli of blue horizontal branch stars and RR Lyrae stars (i.e. Table 2 in the paper) can be found in the data/ folder. Table 3 is the RV and metallicities of member stars in Palca stream.

The STAN model used to model the 2-D density distribution of stars with splines, together with the derived stream parameters (including stream track, stream width and stream surface brightness) can be found in stream_params/ folder. See fits file header for details on each column.

The best-fit stream and its associated orbit can be found in dyn_model/ folder. The columns are described in the header of each file.
