... VOLUME**, **YEAR OF PUBLICATION** **NAMES OF EDITORS** Multiscale Structure in Dust Reflection and Cold H i Steven J. Gibson National Astronomy and Ionosphere Center Abstract. I present 2-D angular optical dust reflection tracing the H analysis reveals a uniform p ower-law in scale, from tens of parsecs down to p ower sp ectra of cold H i emission and i in the Pleiades reflection nebula. ... However, H i and dust should be well mixed in cold gas, so dust may trace H i structure at fine scales. ...

... 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. ...
