This plot
The difference between the first raw bias and the second raw bias (in
ADU) shifted by 10x10 pixels, is computed (per port). 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.
General information
Click on any of the plots to see a close-up version.
If applicable, the latest values from Paranal ops logs are plotted as blue dots. More information about those values, including a download option, is available in the OPS column.
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 ↓)
