This plot

This plot visualizes the daily data volume, in compressed MBytes, created by VLT and VLTI (plots 1 and 2), by VISTA (plot 3) and by the VST (plot 4). The data volume is read from the ngas_files database table. It refers to compressed files and represents the data volume relevant for transfer. Since July 2008, VLT/VLTI data are transfered via the internet, before they were sent on disks. Since March 2012, the EVALSO fibre link serves all Paranal data (including VIRCAM and OMEGACAM) over the internet.

Plot 1: The data stream is divided into "ALL" data; "SCIENCE" (all data acquired between mjd.00 ... mjd.40), and "CALIBRATION" (all other data).

Plot 2: The data stream for instruments with burst modes. Peaks almost always refer to burst mode observations of a single instruments. That instrument can be identified in this plot.

Plots 3,4: As plot 1, the VIRCAM and OMEGACAM data streams are divided into ALL, SCIENCE and CALIBRATION.

Until 2011, the thin broken line in the history plots marks the data volume equivalent to a 10.0 Mbit/s continuous transfer (before EVALSO, this was the bandwidth for data transfer of the connection Paranal - Antofagasta).  

General information

Click on any of the plots to see a close-up version. The latest date is indicated on top of the plot, data points belonging to that date are specially marked.

If configured,

  • statistical averages are indicated by a solid line, and thresholds by broken lines
  • outliers are marked by a red asterisk. They are defined as data points outside the threshold lines
  • "aliens" (= data points outside the plot Y limits) are marked by a red arrow (↑ or ↓)
  • you can download the data for each parameter set if the 'Data downloads' link shows up
