This is intended to be a quick start guide for using the current skimmer version (v6r0p1) to extract merit/digi/recon events from real data as well as construct event lists. Event lists (test file with "Run EventId" pairs) may be used to drive the WIRED event display. FRED needs the explicit digi and recon files to read.
Two simple cases will be illustrated:
Note that at some point the web interface to the skimmer will be able to handle these functions so this is but a stop-gap measure until the web interface is ready.
There is much more the skimmer can do but this guide does not (yet) cover any of that functionality.
