LT and \({\Delta }T_{\text{ss}}\) dependency of the phase lag of the H component between HVD and the five test stations. Positive values indicate that the phase of the data was delayed with respect to the reference data. The color-coded dots indicate the location of the HVD station with respect to the \({\Delta }T_{\text{ss}}(\text{HVD})=-2\); blue dots show events satisfying \({\Delta }T_{\text{ss}}(\text{HVD})\ge -2\) and red dots show events satisfying \({\Delta }T_{\text{ss}}(\text{HVD})\le -2\). The red and cyan vertical lines show sunset times at the summer solstice and the winter solstice, respectively
