        1) Coronal Plasma Compressibility (Coronal Hole) Observation

        Sequence: 03.01_Li_CH1.tcl

        SCI_SPEC: The coronal hole study is to investigate the solar wind 
                  outflow and temperatures above coronal holes as the solar 
                  activity is declining. The goal of the study is to 
                  investigate characteristics of the solar wind plasma in 
                  such a phase.  Since current coronal holes are not clean, 
                  the observation will also allow the determination of outflow 
                  speed and ion temperatures of denser channels hidden in 
                  coronal hole structures.
