Data Status and Revisions Some of the information on this archive is still in a preliminary state. This is denoted by the alphabetic revision numbers in the filename (e.g., RA, RB, etc.). The preliminary data is NOT adequate for any publication use. Please contact the PI for any use of the preliminary data. All files with numeric revision numbers (e.g., R0, R1, etc.) have undergone QA/QC and are considered appropriate for scientific analysis. Any future updates to files will be evident by new revision numbers in the filename with relevant associated comments in the file header. Guidance For Data Users   For responsible scientific use of the data sets provided in this archive, data users are strongly encouraged to carefully study the file headers and directly consult with the instrument PIs. Please acknowledge the data source and offer co-authorship to relevant instrument PIs when appropriate.
