Table 4 Summary of the observations presented in this paper
From: Solar terminator effects on middle- to low-latitude Pi2 pulsations
Dawn | Dusk | |
|---|---|---|
H phase | Almost constant; larger dispersion at middle latitude | Almost constant |
D phase | Phase reversal in 0.5–1 h after sunrise; larger dispersion before the reversal at middle and very low latitudes | Phase reversal in 1–2 h before sunset at low latitudes but with weaker tendency than the dawn phase reversal; no systematic change at middle and very-low latitudes |
H amplitude | Tendency to decrease toward noon but at very low latitude increase after sunrise | No clear trend |
D amplitude | Increases toward noon; increases with latitude except at middle latitude | Increase begins at 17 h LT or 2 h before sunset; increases with latitude except at middle latitude |
D-to-H amplitude ratio | Increase begins at sunrise and peaks at 2 h after sunrise except at middle latitude; increases with latitude except at middle latitude | Increase begins at 17 h LT or 2 h before sunset and peaks at 19 h LT or sunset except at middle latitude; weaker terminator dependence than the dawn terminator; increases with latitude except at middle latitude |
