... The molecular lines group at Arecibo Observatory consists of Chris Salter, Tapasi Ghosh and Robert Minchin. ... The molecular line group at Arecibo Observatory started in 2006 with a proposal to carry out a spectral census of the star-burst galaxy Arp 220 . ... However, the most interesting discovery came from the observations of the polar ring galaxy, NGC 660. ... Molecular Lines in NGC 660 Arias de Saavedra Benitez et al., ...

... 2.3 Data acquisition Spectra generated by the Multibeam correlator contain the usual structure seen in spectra from other H i instruments: a bandpass spectrum which is the sum of the sky , ground and receiver temperatures multiplied by the product of the filters in the receiver chain; superimposed on this is a noise ... Note also that sources extended much beyond ,40 arcmin can be imaged poorly in HIPASS images because of the bandpass sidelobe effect described in Section 3.3. ...
