I attach an spreadsheet with the calibration data of F0 LDVT. The following applies:

1. Nominal position: 11.5 mm.
2. Calibration factor: 0.147 µm/count.
3. Offset to set in the medm screen: +585 counts.
4. Linear range: 4 mm total, [ -2.5 , 1.5 ] mm from the nominal position.
5. The slope of the line shown in the plot is negative because the position reference is above the keystone and the gap increases as the keystone goes down (see picture in the spreadsheet). Nevertheless, the calibration factor is written as positive in the medm screen.
6. The medm screen as been modified already.
