VELO Upgrade Conference Material
This page is updated with useful figures and diagrams for preparing presentations.
Many figures come from the Upgrade TDR, which is also directly browseable at the following link
https://svnweb.cern.ch/cern/wsvn/lhcbdocs/Publications/TDR/Velo/UpgradeTDR/latest/latex/
Additional figures with physics results are added after approval in the VELO Upgrade meetings.
1) Attach the images as .pdf and .png, using the attach button at the bottom of the page. If you do not have the .png you can use linux command convert to make it. convert mypicture.pdf mypicture.png.
2) Copy and paste a line for an existing plot into the relevant section. Edit the name of the plot for both the .png and the .pdf. You may find it easier to do this in the WYSIWYG layout - hit the 'Edit TWiki markup' button (looks like a pickaxe).
3) Edit the brief description of the plot. Add your name so you can be contacted in case of queries.
