Considerable progress was made in making the control of the observations and the data reduction user friendly. Due to the complexity of the OTF observing mode we advise proposers without a demonstrated experience of this technique on the 30m telescope to contact, or involve in their proposal, an astronomer with such experience. Frequency switching is available. At present, up to 3 receivers can be frequency switched simultaneously.
Baselines are ordinarily flatter when using one single receiver.
Many proposals underestimate the time needed to carry out their observations, even under excellent weather conditions. We ask you to pay special attention to this matter as a serious time underestimate may be considered as evidence for insufficient proposal preparation.
