234U-230Th legacy data

[BrendaLHall]

Hi, I'm new to ET Redux and am having trouble using it to calculate 234U/230Th ages with data already at hand. I assume that is through the legacy data set option (Project > New Project Legacy Data Table> U Series legacy data). However, I have been unable to make this option work, probably because I don't have the format of the input table correct, and I couldn't find any documentation. Is there an example input table that mine should look like (what the different columns should be, etc...)? Is there documentation for U-Th? Thanks.
