This plot

Trending plots for monitoring the coefficients of the mask to CCD transformation.

The transformation is as follows:
X = a(xx)*x + a(xy)*y + x(0)
Y = a(yx)*x + a(yy)*y + y(0)
with (x,y) being mask coordinates in mm and (X,Y) CCD coordinates in pixel. X direction is along the slit orientation, y direction is perpendicular to the slits (i.e. in dispersion direction).

These trending plots show the time evolution of x(0) and y(0). x(0) should be within +/- 2 pixels around the average, y(0) within +/- 1 pixel. These thresholds are indicated in the plots. The procedure in case of violation of the thresholds is described on the SciOps Wiki pages.

Template ID: img_tec_MaskToCcd. Pipeline recipe: vmmasktoccd.  

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
