KVN Single Dish Observations


Single dish observations with KVN radio telescopes can be conducted either at individual KVN radio observatory or at the KVN Array Operation Center in KASI, Daejeon. Graphical user interface is available for the observations. Observational data are stored in CLASS (Continuum and Line Analysis Single-dish Software) format. The CLASS is one of Gildas packages developed at IRAM observatory. KVN field systems understand Python languages so that Python scripts may be used for the observations. In principle, PIs are supposed to conduct their own observations. The following observational modes are available for various purposes:

Cal and SkyDip for calibrating the data, Position Switching, Frequency Switching, Grid Mapping, Five Pointing, and Focus for spectroscopic observations, Cross Scan and OTF for continuum observations.

Continuum polarization observations and spectroscopic observations can be automatically conducted using Python scripts. Simultaneus multifrequency observations are available either at four frequency bands (22, 43, 86, 129GHz) in single polarization (LCP or RCP) or at two frequency bands in dual polarizations. Source catalogs are in a format readable by ASTRO software, one of Gildas packages.
