Welcome to the SLD Offline Run Check SystemWelcome to the SLD Offline Run Check SystemThe goal is to monitor the data quality promptly as the production processing wends it way from the online tape to full reconstruction. It is the responsibility of the "non-expert" on each shift to run through this checklist. Serious data problems are to be reported ASAP to the run coordinator. Notice of bad or questionable runs flagged in the checking process will be passed on to the Commissioner and the offline processing crew automatically via e-mail.
You are responsible for any runs whose processing finish during your shift period. The easiest way to determine this is to use the links from the checklist below. If some of the runs are 'catch-up' processing on older missed runs, concentrate on the runs from the day/previous day that are most time critical to report on.
Once the end-run button is pressed in the online, the acquisition (ACQ) data tape is released for further processing in the SLACVX cluster.
The SLDPM server is notified that the tape is ready for processing. It copies the tape to disk, followed by running a PASS1 filter, followed by a full reconstruction and PASS2 filter. The current status of processing can be ascertained from the Offline pages of the SLD Status Display.

(*) This stage runs vertexing code (ZXFIND) on all the PASS2 output events for a given day. It looks at the primary vertex position, gamma conversions and K-shorts, and track muliplicities and VXD linking efficiency. (Default parameters are used in ZXFIND.)
