- Documentation for IFT since LST was installed:
- Proposed solution for time delay from Paolo Musico and Saverio Minutoli(Jan.25, 2005)
- The IFS firmware was modified and uploaded to resolve the timing split between RPC and LST due to the delay in LST (March 2005). This link to the directory containing the new firmware information, but first read the README file.
- The IFT delays can be adjusted with jumpers following this guideline.
- LST was installed for sextants 0,2,3,5 by Dec.2006 and IFT timing was aligned in Jan.2007 before the run 6 data-taking.
