The table gives number of rocks and their surface area as a function of rock diameter. The far field distribution was adjusted to match the near field distribution over the smaller size ranges. The values were derived from table VL0SURFS.TAB. This file is the same as VL1NORML.TAB except that two 'outcrops' have been omitted.
