Comments:
- Note that the system temperature at this frequency depends strongly on weather conditions!
- The new gain curve (Feb 2007) was corrected for opacity. Because of the previous point it is always recommended to correct data at 1.3cm for opacity.
- Typical zenith tau values range from 0.05 to 0.2. An option might be also the use of data from the water-vapour radiometer.
