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.

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