Segment database documentation pages

Introduction

Interferometer state and data quality information is stored in the LSC segment database. The goal of the LSC segment database is to allow the storage and retrieval of data quality information, as well as interferometer state information, derived from the state vector channel.

The LSC segment databases is designed with the following requirements:

  1. Accessible to online analysis: The segment database should be accessible for insertion of data quality flags by online DMT monitors, insertion of state segments by the publishing scripts and retrieval of the information by online analysis programs.
  2. Accessible to users: LSC users should be able to easily query the information in the segment database, and authorized users should be allowed to insert data quality information into the segment database.
  3. Ability to revise information: Data quality segments may need to be modified or deleted after they have been inserted or new data quality flags added. It should be possible to revise DQ segment information.
  4. Preserve history and record pedigree: If segment information is changes, the history of these changes should be preserved. It should also be possible to determine where the segment information came from, either a program or a human.
