| Abstract: |
The Murchison Widefield Array (MWA) is a new low frequency radio telescope
operating on the Square Kilometre Array site in Western Australia. MWA
is generating tens of terabytes of data daily. The size of the required data storage
has become a significant operational limitation and cost. We present a simple binary
compression technique and a system for the floating point visibility data
developed MWA. We present the statistics of the impact of such
compression on the data with the typical compression ratio up to 1:3.1. |
