This plot displays the monthly data volume, in compressed GBytes, created by VLT, VLTI and the survey telescopes. The data volume is read from the ngas_files database table. It refers to compressed files and represents the data volume relevant for transfer.

The data stream is divided into "ALL" data, "SCIENCE" (all data acquired between mjd.00 ... mjd.40), and "CALIBRATION" (all other data).

A continuosly sustained 10 Mbit/s bandwidth corresponds to 3240 GB on this plot. The big increase as of 2014-02 is due to the onset of MUSE data production. This instrument produces more data than all other VLT instruments together and is monitored separately in plot #2.

Note: The latest data point in the current plot usually refers to a month which is not yet finished. Its value will therefore continue to increase until a new last month starts.
