26. n a similar way to One Hour It still shows one hour of data per line but it shows 24 lines of data from a single station The image is scaled to fit the available screen area in your web browser The control panel at the top of the screen is slightly different to One Day as you now use the plus and minus buttons to step through days rather than hours and you can select which station to view from a list which is arranged by sub networks 300km EA LLL Get File The signal amplitude is scaled based on the average signal level from the first hour of data If you need more or less amplitude resolution use the Amplitude and buttons in the orange section of the control panel 16 The blue markers throughout the day indicate eqServer s automatic event detections on that day which may or may not involve the station you are viewing If the station you are viewing triggered during that day you will see a red vertical line at the trigger time As with One Hour you can click on an event of interest and see a pop up window showing three minutes of data from that station and the data from stations within 300km Simply click on the Get File button to download the waveform files For the data download you can adjust the number of stations that are downloaded by selecting a distance from the drop down menu in the blue section the default being 300km as per the preview 6006 v T e JENM
27. n readable text field to help you find stations using relevant keywords The owner of a site may be different to the operator of the site and these are usually short codes that usually relate to the international network code such a GB for the British Geological Survey or AU for Geoscience Australia The start dates are useful for historical records and end dates are used to ensure only current stations are plotted on the maps when setting up sub networks To edit or delete station enter the exact station code proceeding with caution when deleting a station as the action is immediate and non reversible 12 Live Data The Live Data display web page displays a high resolution image of the last hour of data received by eqServer The image is suited to widescreen television displays that have a screen ratio of 16 9 but the image is automatically scaled so that it fits to the browser window resolution If your browser window is wider or taller than this ratio you will see a gap at the right or bottom of the image Most web browsers have a full screen or presentation mode that will hide the navigation and tool bars so that your screen will only show your seismic data The Google Chrome browser has a very clean presentation mode that is well suited for showing this page on an LCD television display The web page automatically refreshes every 30 seconds To prevent image burn in we do not recommend the use of plasma
