# MSL SAM data in the PDS Geosciences Node, including TLS products (2012 onward)

Raw EDR products are "safed" but not formally archived or peer-reviewed; derived RDR products come at levels 0, 1A, 1B and 2 (composition and abundance). MSL Release 42 (3 August 2026) covers sols 4710–4843. The published methane values with confidence intervals are in the supplementary tables of the Webster et al. papers. Supports re-fitting of TLS spectra (the R3 triplet), housekeeping and press
