Data supporting the figures as follows:

Fig.4-i			Electrical resistivity of selected materials for the STAR resistojet heater. The materials in analysis are highlighted in orange.
				i = 1 (Inconel 718); i = 2 (AISI 316); i = 3 (Re); i = 4 (Ta); i = 5 (W)		
Fig.7-i			Specific impulse efficiency optimisation for the three cases in analysis, as function of the diverging angle of the nozzle.
				i = 1 (Inconel 718); i = 2 (Ta); i = 3 (Re);	
Fig.11-Ii*		Ignition of STAR-Inc from cold gas stationary solution. Maximum structural temperature (solid line) and Xe stagnation temperature at the inlet of the nozzle (dashed line) are shown at four current levels. The MOT of Inconel 718 is represented with a horizontal dashed line.
				i = 1 (I=17.6A); i = 2 (I=24.4A); i = 3 (I=29.7A); i = 4 (I=34.2A)		
Fig.12-top-Ii*		Ignition of STAR-Ta (top) and of STAR-Re (bottom) from cold gas stationary solution. Maximum structural temperature (solid line) and Xe stagnation temperature at the inlet of the nozzle (dashed line) are shown at four current levels. The MOT of the two materials are represented with a horizontal dashed line.
Fig.12-bottom-Ii*	Ignition of STAR-Ta (top) and of STAR-Re (bottom) from cold gas stationary solution. Maximum structural temperature (solid line) and Xe stagnation temperature at the inlet of the nozzle (dashed line) are shown at four current levels. The MOT of the two materials are represented with a horizontal dashed line.
Fig.13-i*		Bang-bang heating cycle of STAR-Inc with two current levels corresponding to about 25 W and 50 W of electrical power.
				i = 1 (top subfigure); i = 2 (bottom subfigure)
