Cold gas radial transport in VELA-g3 with different stream selection thresholds. The top and bottom rows show the radial mass flux, F_r (in units of ℳ/t_dyn) in the metallicity- and streamline-based selections, respectively, applied to VELA-g3 disks, with the left, middle, and right panels, respectively, focusing on streams, non-streams, and all cold gas. The solid lines indicate the medians and the envelopes represent the 16^th − 84^th percentile variations. Results are shown for Z_cut = p^th percentile, where p = 99 (blue), 95 (yellow), and 90 (red), and d_cut = 0.05 (cyan), 0.1 (green), and 0.2R_d (brown). Here, Z_cut is the threshold metallicity from the mass-weighted metallicity distribution between r = R_d to 2R_d and z = −H_d to H_d used to distinguish between streams and non-streams in the metallicity-based selection (see Section 5.2.1). Similarly, d_cut is the minimum distance by which gas cells must travel inward over the average disk dynamical time to be classified as streams in the streamline-based selection (see Section 5.2.2). While the median stream signal is slightly larger in magnitude for larger values of Z_cut and smaller values of d_cut, the dominance of incoming streams in the cold gas radial mass flux is insensitive to the exact values adopted for the thresholds in the different stream selection procedures.
