2008-04-01: The new pipeline calculates the master bias differently from the old one, which results in an increase in the measured read-out noise of the master frame.
*Data sources: QC1DB: QC1 database; LOCAL: local text file | **OPS: to indicate that OPSLOG data are included
This plot
For the master an expected master bias noise is calculated from the
ron of the raw data, divided by the square root of the number of
frames that were used to create the master bias. Then the population
standard deviation of the pixel values of the master bias is
determined, excluding all pixels that differ more than three times the
expected ron from the median level of the master bias.

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 ↓)
