Subject: Hex: A Correlator Data Quality Package

"Hex" is a package for monitoring the quality of the data produced by the ATA correlator. It comprises a set of scripts for making standardized observations and then automatically analyzing them to understand the array performance. The data quality metrics include paremeters such as:

  • Antenna system equivalent flux density (SEFD)
  • Antenna sensitivity
  • Antenna primary beam shape

This book describes the design of the hex package and how to use it.
