This plot

The difference between the first raw bias and the second raw bias (in ADU) shifted by 10x10 pixels, is computed. This is the combination of fixed pattern noise and read out noise (scaled by sqrt(2)). The population standard deviation of this difference is computed and divided by the square root of 2. The read out noise contribution evaluated as QC OUTi RON is then quadratically subtracted from the total noise.

The latest date is indicated on top of the plot, data points belonging to that date are specially marked.

If configured,

statistical averages are indicated by a solid line, and thresholds by broken lines

outliers are marked by a red asterisk. They are defined as data points outside the
threshold lines

"aliens" (= data points outside the plot Y limits) are marked by a red arrow (↑ or ↓)
