Default NOESY peak signs
NOESY peak signs

I am new to NOESY, so I have a number of question about interpreting resulting 2D spectra. Mixing time is 300 ms, substance - lactic acid. I have a NOESY spectrum (pulse program - noesygphp) with several peaks having sign structure as:

- -+- - I know that the peak with the sign "-" corresponds to dipolar-dipolar interaction, "+" - to chemical exchange. But I don't understand what my result means.
