Behavior of the load Love numbers used to calculate the response to LPIM and RPIM. The load Love number for \(\tau = 2\) kyr determined from the VM5a model (orange lines in Fig. 6) is shown as the gray-colored symbol in each panel, for comparison with those obtained from the subsurface structure model (Table 3 and Fig. 7). a The variation in \(-{\dot{\delta }}_n(\tau )\) with degree (n) and time (\(\tau\)). b The variation in \({\dot{h}}_n(\tau )\) with degree (n) and time (\(\tau\)). c The variation in the ratio of \(-{\dot{\delta }}_n(\tau )\) to \({\dot{h}}_n(\tau )\) with degree (n) and time (\(\tau\)). d The variation in \(-{\dot{\delta }}(\psi , \tau )\) with angular distance (\(\psi\)) and time (\(\tau\)). e The variation in \({\dot{h}}(\psi , \tau )\) with angular distance (\(\psi\)) and time (\(\tau\)). f The variation in the ratio of \(-{\dot{\delta }}(\psi , \tau )\) to \({\dot{h}}(\psi , \tau )\) with angular distance (\(\psi\)) and time (\(\tau\))
