DELANA, Event Reconstruction and Analysis software

New-Delana link to documentation has been deleted on the request from Markus Elsing. It was out of date and we have firm promisses that new documentation will be provided in due course.

DELANA is the main DELPHI software for Raw data event processing concerning Real and Simulated Data. This includes data decoding, Pattern recognition, track reconstruction, Event tagging.

DELANA code needs a well kept (updated) DELPHI Detector description and Calibration Database to include detector status, calibration/Alignment constants and individual detector code, capable of understanding the database structures and contents correctly.

The programme is built similarly to DELSIM, with a main steering calling individual detector codes and uses DDAPP for the reconstruction.

The main output stream is (since 1991) Full-DST. Additional output streams are provided, as needed, for detector checking, luminosity (SAT), alignment, etc.

The I/O is managed via the UX-package to ensure correct data transmission.

To create the Full-DST output it calls PXDST.
This is usually activated on DELFARM to minimize processing steps and data volume.
