The SumLengthDistributionData model data is a list of two elements; the Data, which are similar to LengthDistributionData but added the Layer resolution column and summed vertically; and the Resolution, which is a table of the three columns Station, Layer and Haul containing the link between the vertical resolution variables before summing.

This data type is produced by SumLengthDistribution with input LengthDistributionData from LengthDistribution. SumLengthDistributionData is used in MeanLengthDistribution with output MeanLengthDistributionData. See DataTypes for a list of all StoX data types produced by RstoxBase
