	1) Low-Latitude Coronal Holes and Coronal Hole Boundary

	Sequence: 08.04_WHI_CH.tcl

	SCI_SPEC: To understand the origin of the solar wind from 
                  low-latitude coronal holes, including coronal hole 
                  boundaries by characterizing the physical properties 
                  of the coronal plasma (temperature, density, abundance,
                  outflow velocity) with coordinated multi-spacecraft and
                  ground-based observations in order to investigate the 
                  physical processes that lead to the origin of the solar 
                  wind. UVCS will position the slit to cover the coronal 
                  hole and boundary regions, at the limb, with three roll 
                  angles and run observations in H I Ly-alpha and 
                  OVI 1032/1037 at a height of 1.7 Ro.
