Fitting the three main lines in the Chandra spectrum: 12.13, 15.01, 18.97 with porous models

Fe XVII 15.014 - already had done some preliminary tests - issues include wavelength range over which to fit (15.06 vs. 15.10 made no significant difference), and what terminal velocity to assume

For now, v_inf = 2200
