Assumptions: 	Ti and Vphi measured by CXRS.  Zeff profile 
		determined from measurement of carbon density 
		proifle by CXRS normalized to single-chord VB.  
		Electron temperature measured by ECE radiometer, 
		and Ne by 10-channel interferometer.  
Shot Desc.: 	This is a modest-current (1.4 MA), low-power (14 
		MW) supershot plasma that is perturbed by a 
		deuterium pellet at 3.85 seconds, about 350 ms after 
		the start of NBI.  The pellet significantly raises the 
		electron density: the total electron population 
		increases 74% by the pellet.  The pellet also appears 
		to have a long-term effect on the plasma edge 
		density; although the plasma density decays on a 
		time scale ~100 ms, the edge density remains 
		elevated by 10-20% relative to the pre-pellet value.  
			The temperature and chii response to this 
		perturbation of the ambient temperature (LTi) and 
		density (Lne) gradient scale lengths provides a test 
		of proposed transport models, especially those 
		having a strong marginal stability character.  A 
		limitation of this discharge is that the density is 
		modest: before the helium puff, nebar = 2.2e19 and 
		Neo = 3.3e19, and the Zeff is rather high, 3.2 on-axis.  
		Consequently in the pre-pellet phase, the beam 
		density in this plasma is significant, comparable to 
		the thermal-ion density.  This shot is a member of 
		scan SS1 which consists of various perturbations to 
		supershot plasmas with pellets and gas puffs.
