Frequencies available with the EVN
The principle wavebands/frequencies which can be observed with the EVN include:
| Waveband | Default central frequency |
|---|---|
| 18 cm | 1664 MHz |
| 13 cm | 2268 MHz |
| 6 cm | 4992 MHz |
| 5 cm | 6668 MHz (Methanol), 6030 MHz (OH) |
| 4 cm | 8418 MHz |
| 1 cm | 22230 MHz |
Observations are also possible at some stations at:
| Waveband | Default Central Frequency |
|---|---|
| 90 cm | 327 MHz |
| 50 cm | 610 MHz |
| 21 cm | 1416 MHz |
| 2 cm | 15362 MHz |
| 7 mm | 43214 MHz |
A reasonably complete description of the frequencies available for VLBI observing is provided with SCHED (in the file '$SCHED/catalogs/freq.dat'), the standard program used for scheduling EVN observations. A more condensed description of the wavebands available at the EVN observatories can be found in the EVN status sheet.
The frequencies available at each of the observatories are presented graphically here: on a linear and a logarithmic frequency scale. The regions shaded red are the frequencies which are accessible to the various EVN observatories according to the SCHED catalogues (which are not quite complete). The VLA and VLBA frequencies (except 86 GHz) are indicated in blue for those interested in global observations. The bottom entry, in black, is a composite of all the frequencies available at one or more EVN observatories. These images are also available in postscript format (linear, and logarithmic).
