Contextual information: Sample ID, Site name, Type of settlement, Trench number, Context number, Chronological details, Details of climatic period (Before, During or after 4.2 ka BP), vessel details (including type of sample, type of vessel and other vessel characteristics such as rim diameter, shape, finishing, etc.). GC-MS results: The lipid yield and concentration of every fatty acid present in the sample (from C12:0 to C28:0) is provided. The presence/absence of n-alkanes, alcohols, cholesterol contamination, phthalates and sulphur are also included, as are the ratios of C16:0/C18:0. GC-C-IRMS results: The d13C values of C16:0 and C18:0 fatty acids as well as the D13C (d13C18:0-d13C16:0) values are provided.
