Negative polarization properties of regolith simulants - Systematic experimental evaluation of composition effects

<p>This dataset refers to the paper &quot;Negative polarization properties of regolith simulants - Systematic experimental evaluation of composition effects&quot;<br> DOI: https://doi.org/10.1051/0004-6361/202243844</p> <p>Different dust mixtures were created to simulate the mineralogical complexity of asteroids using different mineral endmembers: silica, magnetite, forsterite, spinel, graphite, fayalite.</p> <p>Binary mixtures and ternary mixtures were created using the end-members, and this dataset collects all their polarimetric curves. Furthermore, aggregate of less than 0.2mm and more than 2mm (only for silica-graphite mixtures) have been created and measured.&nbsp;</p> <p>Each .txt file shows the data of a polarimetric curve. The columns correspond respectively to:</p> <p>#phase_angles[&deg;]&nbsp;&nbsp; &nbsp;#Q/I&nbsp;&nbsp; &nbsp;#U/I&nbsp;&nbsp; &nbsp;#V/I&nbsp;&nbsp; &nbsp;#DOLP&nbsp;&nbsp; &nbsp;#DC&nbsp;&nbsp; &nbsp;#delta_Q/I&nbsp;&nbsp; &nbsp;#delta_U/I&nbsp;&nbsp; &nbsp;#delta_V/I&nbsp;&nbsp; &nbsp;#delta_DOLP&nbsp;&nbsp; &nbsp;#delta_dc</p> <p>&quot;delta&quot; refers to the error associated with the measurement, obtained by the repetition of the measurement for different azimuthal angles of the sample (see paper for more detailed description).&nbsp;</p> <p>The SEM images are the one corresponding to Fig. 2 and 3 of the paper.</p>
