19 Sept 2000 The comparisons between UVa's Sierra impactors, UVa's bulk filters, and UH's MOUDI were redone using UVa's corrected data set. The old files cw1.ps throught cw10.ps and cwo1.ps through cw10.ps were deleted. The new set of revised plots are named cw1rev.ps through cw10rev.ps and cwo1rev.ps through cwo10rev.ps. The file names stand for Comparison With (cw) the sept 15 data point (which looks to be contaminated) and Comparison WithOut (cwo) the Sept 15 data point. Note that UH did not run any of its samples for oxalate.
