The data has been treated to remove some cross talk between different sectors (look directions) and mass channels. The data has been treated to remove background and compensate for the differing onboard background subtraction. The data set also contains a ZERO value which provides an uncertainty estimate of the zero level of the data. MARS RPC-ICA Data Archive ========================= a) DATA ======= CODMAC Level/Type Data Type Data Content 4 / Resampled Data table CALIBRATED and EDITED data of ICA The data can be found in directories of this type: DATA/CORR/2004/SEP/D23 DATA/CORR/year/month/Dday/*.TAB (ICA data files) *.LBL (PDS LABEL files for the data files) All data files are in ASCII text format. b) Supporting files =================== Supporting files for the Archive user include PDS descriptions, documents, and searchable indices. These have been organized into five directories one level below the root: CALIB, CATALOG, DOCUMENT, GEOMETRY & INDEX.

Consequently, the layout of this volume and the labels for each file conform the PDS guidelines.
