README file for SLSTR S3D filter functions
June 4th, 2025

Draft measured spectral responses of the seven standard channels S1 - S9
in the focal plane of the SLSTR FM02 instrument, to fly on the Sentinel 3D platform.
The responses of the fire channels F1 and F2 are identical to the responses of standard
channels S7 and S8. The responses are derived from measurements taken during a
spectral calibration campaign conducted at the STFC Rutherford Appleton Laboratory
(RAL) in December 2019 and January 2020, and July 2021.

The results of those measurements are described in the
document S3R-RP-RAL-SL-00056 - SLSTR D FPA Spectral Calibration - 1.0.pdf .
