2. 2 Overview What’s included in CondDb.  Alignment  Readout  Slow/fast control  calibration Ex/DetCondExample/v7r7 (sort of old ver.)  Example package for LHCb CondDb. Ex/DetCondExample/v11r2 (recent ver.)  A little bit reorganized structure.

6. 6 Xml-based Data base CondDb uses xml files.  Examples are shown next slides Xml string can be put to actual Db server via C OOL package. What if we need to access Heidi’s hardware D b from Gaudi framework?  It’s possible to convert conventional Db to Xml Db. Pmt calibration, …  Is it safe to have mutiple Dbs?

11. 11 Running test program I could run a test program that reads file-based Db and prints out the values. I couldn’t test example that works with actual Db. The package includes:  Algorithm that fills xml to Db.  Algorithm that loads xml from Db.  A script that creates Db.  A script that copies xml to Db.

14. 14 What we’ll need Alignment data  It should be given to reconstruction package(i.e. trac ker finder, track fitter) and calibration package. DAQ Conditions/calibration  It should be given to Sergei’s Readout packages. Cosmic calibration  Need calibration package that calculate calibration d ate.  The calibration output will be used to other packages.

15. 15 Mapper software Using root Read Leo’s manual scan data text file in new Framew ork.  Some of code is imported from old one.  Plan to add a piece that handle binary data from real mapper DAQ. What’s been done  Basic framework and data class  Data is organized into tree structure, so easy to handle for furt her complicated analysis  Pedestal curve is fitted and pedestal shift is calculated.  Transverse scan fit is progress.
