The measured Na i absorption depth of HD 189733b (CLV effect corrected) and the modelled line depth change due to the CLV effect.
|Passband (Å)||Planetary absorption depth (%)||CLV effect model (%)||CLV overall-transit/|
|(from this work)||mid-transit||limb-transit||overall-transit||planetary absorption|
|0.75||0.414 ± 0.032||–0.082||0.328||0.120||29%|
|1.5||0.222 ± 0.018||–0.071||0.257||0.091||41%|
|3.0||0.155 ± 0.011||–0.048||0.126||0.038||24%|
Notes. The values are obtained using the average of D1 and D2 lines. Here, the CLV effect are presented in three values: mid-transit (phase = 0), limb-transit (where the line depth change is the largest) and overall-transit (average of all the line depth changes in transit).
