... This is particularly true for columns at low energy, because of charge transfer efficiency variations from one column to the next. ... To avoid wrongly detecting columns as bad (either dark or bright), the observed dispersion in the distribution is used to compute the significance of an excess assuming a Gaussian distribution. ... The cost of this security is to detect less easily groups of bad columns/rows, because the observed dispersion is large even when the tested column/row is discounted. ...
