PROJECT SUMMARY Intellectual Merit: In Puerto Rico, education and research in Astronomy-Astrophysics is mostly conducted at the University of Puerto Rico and at the National Astronomy and Ionosphere Center. UPR is mostly an undergraduate teaching institution, and NAIC is a national facility where all observing time is granted via peer review process, open to all researchers. ... Through the outreach program, public awareness of radio astronomy and indeed of physical sciences will be much enhanced. ...
... 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. ...
