+### Generated Transmission Spectra (POSEIDON)
+Additional transmission spectra were generated from the exported atmospheric profiles in `transmission spectra/profiles/` using the notebooks in `transmission spectra/notebooks/`.

+
+Analysis summary:
+- The transmission spectra compare the four agricultural scenarios (A0, A1, A2, A3) for each stellar environment.
+- The analysis focuses on how increasing agricultural nitrogen emissions (N2O and NH3) modifies spectral features and the total transit depth signal.
+- For TRAPPIST-1e, the spectral decomposition output separates molecular contributions, helping identify which species drive the A0 vs A3 differences.
