... Proposal Type: General Category: Observation Category: Total Time Requested: Minimum Useful Time: Prop osal Title: ABSTRACT: Regular Astronomy Extragalactic 22 Hours 3 hours The Baryonic Content of Extremely Low Mass Galaxies We propose continued HI observations of low mass galaxies to better quantify the galaxy mass function. ... In 2014A, we observed 61 isolated low mass galaxies with Arecibo with masses between 40-60 km/s, tripling the number of observations in this mass regime. ...

... 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. ...
