It has been used from 1985 to 1996 to observe molecular transitions in the cm bands available at this telescope, particularly the H2O line at 22 GHz, the CH3OH lines at 6 and 12 cm, and the NH3 lines at
The istrument has now ceased operations, and this page is here mainly for historical reasons.
The instrument has a total bandwidth selectable from 0.78 to 25 MHz, and 1024 spectral channels. The typical RMS noise, in the 22-23 GHz band, assuming 5 min. integration time and 25 MHz bandwidth, is about 0.7 Jy.
