Notification: fce: electron cyclotron frequencyfci: proton cyclotron frequency fpe: electron plasma frequencyfpi:proton plasma frequency fLH: Lower Hybrid Resonance frequency *The present tables propose the target physics and the necessary data qualities for us to study them. The time resolutions, frequency resolutions etc. in the tables have not been listed under the consideration of the telemetry capacity and the onboard data processing capabilities of the MDP. The listed values are presented only in the scientific point of view. *To the speakers of the morning session Please close your talk with some addition / correction of items in this tables and/or the proposal of ‘new’ pages. Baseline of the PWI target physics and necessary data qualities
