(a) Full Width Half Maximum (FWHM) values of SIMGA Spatial Response (across and along slit) obtained by static measurements performed in laboratory (Gaussian fit to data, [9]) and smearing effect due to integration during motion

	FWHM (m) at 1 Km Across-SLIT (along-scan)	FWHM (m) at 1 Km Along-SLIT (across-scan)
VIS	1.91 (1.88 static)	1.05
SWIR	1.16 (1.13 static)	1.40

(b) SIMGA detector and optical parameters used for simulation (𝑉 = 30 m/s at 1 Km height)
