For each of the input source-list columns X, Y and FLUX: makes a frequency histogram of relative offset.
`Frequency histogram' means that the area under this histogram is equal to the number of rows in the merged list. The axis of the plot is the quantity
where
The interpretation of these quantities in column terms, taking for the sake of an example the spatial coordinate, is
Y,
SIM_Y and Y_ERR.
These histograms are written to tables named REL.
