The STAR experiment

 see db04-issue.pdf for introduction

(previous blog entry was deleted)

 TPC based MIP algo was devised to calibrate BPRS tiles.

Details of the algo are in 1st PDF,

INPUT: st_hysics events from run=9067013

The pair of plots below demonstrates BPRS pedestal residua are very clean once peds for 128 caps are used and this 5% capID corruption is detected and fixed event by event.

Update 2008-11-06: minor naming revisions:

• use crate/crateChannel instead of crate/sequence in bemcMapping
• use rdo/rdoChannel instead of crate/position in smd and prs mapping

Update 2008-11-03: I posted a new version of the schemas. The changes are:

• drop softID field in favor of elementID, as the latter has a special meaning in STAR’s DB API.
• add eta and phi float fields to give the physical position of each element.
• rename module-eta-sub to m-e-s so we can redefine eta as above.
• added PMTbox, MAPMT, and pixel fields in the PRS table.
• renamed fiber to crate in the SMD and PRS tables.

NB Mainly notes for self but posting here will enable others to see too.
