How does AstroImageJ handle detrend correlations?  For example, detrend parameter X-Width_T1 would likely be strongly correlated with detrend parameter Y-Width_T1.  Airmass would likely correlate (to a far lesser extent and less predictably) to FWHM_T1.  Other detrend parameters are completely independent of each other.  How extensive is the logic that AstroImageJ uses to assess such potential correlations and correct for each one appropriately?
