Optical measurement

We use before-run4 optical measuremens from Chris 2011-06-20 file.

Procedure and table of results

We calculate
S1 - 1st short side of 2x1
S2 - 2nd short side of 2x1
L1 - 1st long side of 2x1
L2 - 2nd long side of 2x1

...

  • Problematic measurements are
    • Quad 2, pair 6 - significantly different length of sides
    • Quad 2, pair 7 - significantly different length of sides
    • Quad 3, pair 5 - significantly different width and length of sides
  • All other are consistent with each other within +/-10um.
  • Angles of 2x1 are in the range from -0.46 to +0.44 degree.

Configuration parameters

Configuration parameters are shown in number of pixels.

For 2x1 pairs in each quad

Coordinates of the 2x1 centers

  • Use the same orientation as in optical measurement, center is calculated as an average of 4 corner coordinates
  • All coordinates in pixels
