... multiple records containing an ascii data record header followed by 100 ipps of binary (short) data. ... The data taking program has two input buffers (100 ipps each). ... The power program and clp programs have different transmitter samples: . ... To automatically differentiate between power and clp ipps, the rms was computed (using the I sample) for tx samples 1000 thru 1500. ... The clp ipps had tx samples (so the rms would be large) while the power ipp was blanked (so the rms should be small). ...

... 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. ...
