Supplementary data for: Characterizing the GD-1 Stream with DESI DR2 Data: Thin Stream and Hot Cocoon

Supplementary material to DESI's publication "Characterizing the GD-1 Stream with DESI DR2 Data: Thin Stream and Hot Cocoon" to comply with the data management plan. Directory contains data points for all figures with filenames indicating the figure to which the data corresponds as well as a FITS file for all tables. In all, data for 15 figures and 8 tables (95 total FITS files) is included in the .zip directory.

Users may find the following tables most useful:

• Table1.fits: contains the distance gradient track nodes as a function of phi1.
• Table3.fits: contains the stream track node locations for phi2, proper motion and VGSR tracks.
  • The tracks in version 1 and 2 are incorrect. Please only use Table3.fits in the latest zenodo version (version 3)
• Table7.fits: contains the DESI GD-1 catalog of member stars with membership probabilities. In addition to the columns presented in Table 7 in the paper, this fits file also includes columns for: proper motions and their errors (in both RA and Dec coordinates and phi1 and phi2 coordates),  g- and r-band magnitudes (corrected for extinction), and delta parameters with the stream track subtracted for phi2, proper motions and VGSR.
• Table8.fits: contains the catalog of BHB stars. In addition to the columns presented in Table 8 of the paper, this table also includes columns for proper motions and delta parameters with the stream track subtracted. It does not include membership probabilities as these stars are not included in the Gaussian Mixture Model.

We also incude a jupyter notebook "GD1-DESI-Tutorial-Jarvis.ipynb" to demonstrate the use of our GD-1 member and track tables.

We note that this work has been submitted to ApJ, but results are subject to change after the referee report.
