... Method A simple radiative transfer model representing a HISA cloud with fore ground and background H i emission and background continuum emission is described by the expression T ON - T OFF = T S - T C - p T OFF 1 - e -# , (1) where T ON and T OFF are observed brightnesses on and o# the HISA feature, T S is the spin or excitation temperature of the HISA gas, # is its optical depth, T C is the continuum intensity, and p is the fraction of H i emission lying behind the HISA feature. ...

3. http://www.naic.edu/~phil/mbeam/hipass.pdf
... 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. ...
