      <description>This table contains the raw data used to generate the Water (H2O) concentration data used to creat the simple cylindrical projection maps in the BROWSE folder of this data set.
          These data were collected between 06/04/02 and 04/03/05. Values of 9999.999999 indicate invalid data points. Negative concentrations indicate that the background subtracted during peak fitting was larger than the signal. Negative values are included when data are smoothed.</description>
