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 closeup version.
If applicable, the latest values from Paranal ops logs are plotted as blue dots. More information about those values, including a download option, is available in the OPS column.
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
