This plot

Trending report for median value across master dark.
QC parameter is derived for each detector of the raw dark frames.

On 2016-11-19 (blue vertical line) new CASU pipeline was adopted.

Name:
Fits header: QC.RAW.MEDIAN.MEAN,
QC1 DB: qc_dark_med

Description:
The mean of the raw dark medians. Setup:
DET.DIT=2.0
DET.DIT=300.0

These plots describe:
Fig. 1. chip4: The QC parameter for DIT=2.0 for chip #4.
Fig. 2. chip3: The QC parameter for DIT=2.0 for chip #3.
Fig. 3. chip4: The QC parameter for DIT=300.0 for chip #4.
Fig. 4. chip3: The QC parameter for DIT=300.0 for chip #3.
Fig. 5. chip1: The QC parameter for DIT=2.0 for chip #1.
Fig. 6. chip2: The QC parameter for DIT=2.0 for chip #2.
Fig. 7. chip1: The QC parameter for DIT=300.0 for chip #1.
Fig. 8. chip2: The QC parameter for DIT=300.0 for chip #2.

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
