Separation of signals that should, under some circumstance, be distinguishable. Relative resolution (unitless) is the value of the distinguishable parameter (say, wavelength) divided by the smallest value difference that an experiment can actually distinguish. Absolute resolution (has units) is the smallest difference that can be discerned in a measured quantity.
