IRIS data can be accessed in real-time using the appropriate software and password.
The following conditions of access apply:
- Guest access to the IRIS system is granted for a specified period only.
- Access is granted only to the user or institute named.
- Copies of the software belong to Lancaster University, and should be destroyed after the access period has expired.
These conditions are in addition to the standard `IRIS Rules of the Road'.
- Users must register to use the Lancaster STP data facility, and then request (by email) permission to use real-time access.
- A PC which runs DOS, Windows 95, Windows 98 or NT 4. Windows 2000 may work but is not supported. It is possible to run the software in a Linux DOSEMU window, but again, this is not supported. By default it accesses the COM ports directly but is easily configured to use BIOS calls instead. This will be necessary for NT4.
- A Hayes-compatible modem (sorry, access is by telephone only).
- Approximately 2Mb of free space on drive
- A username and password.
- The software. Authorised users please see the instructions for download and installing the software (restricted access).
If you believe you have a case to use real-time IRIS data please contact us by email. We regret that this facility is restricted to bona fide researchers only. Successful applicants will be issued with a username and password, valid for a specified duration, and be given further information.
The dataview should look similar to this:
Check that the numbers and images displayed are absorption, not received power; look for the words "Decibels Absorption" on the righthand-side. If the words "Riometer Voltages" appear instead then please contact an IRIS administrator who will switch the display into the correct mode for you. If any error messages (flashing red text) are noted they should be reported to an IRIS administrator immediately.
Top left of the display shows the absorption scale. The four squares correspond to images averaged over four different periods: 1 second, 10 seconds, 1 minute and 10 minutes. Each image is composed of 7 × 7 squares, which relate to the 49 imaging beams. Please note that the beam centres are not arranged rectilinearly, so the displayed images are not spatially correct (this is allowed for in the real processing but not the real-time display). The accuracy of the quiet-day curves used by the real-time display cannot be guaranteed, so the values shown must be considered as preliminary data only.
The current absorption values are given in numberical format on the righthand-side of the display. Below this, in cyan, is the data stream from control box which should be ignored.
Other Data Formats
For scientific analysis data or plots may be requested in a variety of formats using the automated data request.
