Since 2021 the uves_cal_mbias recipe is executed with the --pd_noise_compute=TRUE command line option that performs a 2D Fourier transform of each of the five raw BIAS frames and calculates the (not robust) standard deviation and (robust) MAD (median absolute deviation). For each input raw files, both parameters are ingested into the QC1 DB as well as their ratio std/stdmad. In addition the maximum of the five std/stdMAD values (max_ratio) is ingested and monitored here .
The purpose of the analysis is to discriminate statistical noise, and non-statistical noise.

The latest date is indicated on top of the plot.
If configured,
data points belonging to the latest date are specially marked
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 ↓)
