Linear LD u1 and Linear LD u2 are entered in the Data Set 2 .Fit Settings screen.  What is their effect on the final output by AstroImageJ?   For example, if I input the wrong filter in Exofast (say V instead of R), what would be difference in the output of AstroImageJ (both graphically in the plot, and in the Measurements table)?  What specific data (or sets of data) would be in error?  Where are all the places in AstroImageJ where I would see inaccurate data as a result of entering the wrong filter in Exofast?  Thanks.
