This plot

The linearity of the MIDI detector is an indicator if the quality of its response curve. The pipeline calculate the coefficients of the polynomial fit of the average pixel value (over a windowed area) of the detector for 3 different configurations (image, prism and grism). The polynomial fit is: I(t) = A_0 + A_1 * t + A_2 * t^2, where I is the detector level in ADU and t the time in millisecond.  

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
