| R Leo | 3×1015 | 1.2 ×10−8 | ||
| R Dor | 2.5 ×1014 | 0.1 × 10−8 | з×1014 | 0.12×10−8 |
| WHya | 1.2 ×1015 | 0.5 × 10−8 | 1.5×1015 | 0.6 ×10−8 |
| IK Tau | 0.6 ×1016 | 2.5 × 10−8 | 1×1016 | 4.2 ×10−8 |
Notes. For R Leo, the Trot and NAlF are estimated using the PD shown in Fig. 6. For other sources, we used Trot estimated for o Ceti and R Leo to approximate NAlF. For all sources, the H2 density of 2.4 × 1023 cm−2 is used as derived for o Ceti.
