Do we want this per camera by etch? Just link to tracker? (Suggest we have an overview of noise of all modules in a table. Could have Adu/keV as well, but that should get calibrated away for users.)
| typical | |
|---|---|
| noise | 250 eV ? (75 e- or whatever) |
| energy range | about 2-800 keV |
| Pixel size | 50x50 um**2 |
| Array size | 704 x 768 |
| position resolution | foo at 8 keV |
| split photon % | foo at 8 keV |
| etc. |
Measured performance 
Noise (pre-common mode?)
