Definition: incidence and emergence angles are positive with origin at nadir. Emergence angle in transmission is larger than 90° (=180°-i).

- Comments
- The maximal spatial resolution, in the limit of diffraction, was about 5μm focusing the beam with a Schwarzschild–Cassegrain objective ×32. The resolution changes with the wavelenght according to the Abbe's equation.

- Analysis
- Reference spectrum was acquired using near the sample on the diamond compression cell to calibrate the absolute reflectance of our measurements. The spectrum has been corrected from its baseline and normalized to its silicate maximum peak.Data between 2700 cm−1 and 1800 cm−1 are forced to zero as they are not representative of real features due to the sample.
