Table B.1
Summary of basic statistics based on different spiral models.
| Model | On-arm filaments | Off-arm filaments | Number of bones | DGMFs for on-arm | DGMFs for off-arm |
|---|---|---|---|---|---|
| TC93 | 44 | 44 | 8 | 0.173 | 0.171 |
| R19 | 25 | 63 | 6 | 0.200 | 0.146 |
| H21 | 14 | 74 | 3 | 0.155 | 0.178 |
Notes. The first column lists the spiral models used. TC93 for Taylor & Cordes (1993), R19 for Reid et al. (2019), and H21 for Hou (2021). The second column lists the number of filaments associated with spiral arms for each spiral model and the third column lists the number of filaments that are not associated with any arms. The fourth column lists the number of filaments satisfying the criteria for bones. The fifth column lists mean DGMF for filaments associated with spiral arms, while the sixth column lists those “of”f arms.
