This plot

Fixed-Patter-Noise - the largest noise component in the raw frames of the lamp flat-fields. It is determined by the "naco_img_lampflat" recipe of the NACO pipeline (QC.FPNOISE). The data points are separated by the detector readout mode the lampflats were taken with.  

General information

Click on any of the plots to see a close-up version. 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 ↓)
  • you can download the data for each parameter set if the 'Data downloads' link shows up
