FILTER_SIGNIFICANCE

For each filter there is a column for the source significances (signal-to-noise). These values are the averaged values from the individual sources that were merged into a source. The significance will be set to the negative of its value if the averaged corrected count-rate exceeds 1000 count per second and all the magnitudes will be set to null.
