Footnotes:

ND = No dye detected

• = A fluorescence peak is present that does not meet all the criteria for a positive dye result. However, it has been calculated as though it were the tracer dye for background purposes.

• • = A fluorescence peak is present that does not meet all the criteria for a positive dye result. However, it has been calculated as a positive dye result.
