Particle size
The sample was processed at the Instituto de Cerámica y Vidrio (CSIC-ICV) to produce a narrow particle size distribution centered at 3-4 micrometers.

Refractive index
The complex refractive indices of the JSC Mars-1 analogue were retrieved using the JSC Mars-1 XL sample for a wavelength range of 200-2000 nm (see Martikainen et al., 2023). For the wavelengths of the scattering matrix measurements, the values were interpolated as shown by Martikainen et al., (2024).
At 488 nm, n = 1.45 and k =0.00095. At 640 nm, n = 1.5 and k = 0.00065.
