40m RT basic technical information
Spectral observations. These observations are available under several standard modes: position switch and frequency switch. On-The-Fly (OTF) mode will be offered soon (see below). Position Switch observations can be programmed ad-hoc using several phases. The spectral backends are Fast Fourier Spectrometers (FFTs) with 100 MHz, 500 MHz, 1.5 GHz and 2.5 GHz bandwidths with 6 KHz, 30 KHz, 180 KHz and 38 KHz resolution respectively.
Continuum observations. These observations are restricted to total power pointing drifts or focus drifts. Position switch using a wobbler or a beam switch are not available. Currently there are several backends offering a bandwidth of 2.5 GHz, 1.5 GHz, 500 MHz or 100 MHz depending on the observed frequency.
New: New bands and observing modes are available on a limited, shared-risk basis:
Available observing frequencies:
Instantaneous detection band and spectral resolution
Angular resolution (θb) and aperture efficiency(ηA)
The 18.5 GHz expansion of bands Q and W has been done within project Nanocosmos (ERC-2013-Syg-610256-NANOCOSMOS) during 2019.
