Attached, the latest metrology files for the 3 quads at MEC.

Quad0 and Quad2 metrologies should be applied for all experiments after 2016.02.16.

Quad 1 metrology should be applied for all experiments after 2016.04.21.

As always, please use only Mikhail’s curated version; Excel files are known to contain bugs.

Thanks,

Gabriel

Hi Gabriel,

Your file with optical measurements of MEC Quad1 from

2015-04-21 has large Z coordinates even for the 1st point as shown below.

Point 6 with Z=-1095 is definitely problematic. Should we trust to these Z measurements?

Hi Mikhail,

No, the very large numbers (in absolute values) are not correct; sometimes the OGP focuses on other surfaces than the sensor surface. I’ll look into the strange values today.

(If a large fraction of the tiles are not correct, we can easily re-metrologize the offending MEC quad; we only need to remove the front shield. In the CXI camera it’s much more complicated, as written yesterday).

Thanks,

Gabriel

Hi,
Just to make sure there is no labeling mix-up, could you please try the
latest metrology files for the other 2 quads? I’m asking this because 2
weeks ago I received a quad I thought was 1 but was labeled 2
