1. http://www.naic.edu/~phil/optics/shimfeb02/shimming.html
The pitch, roll, and focus errors measured in aug01 can be corrected by rotating the dome by .12 degrees in roll and shimming a linear ramp in pitch of .125 degrees between za=10 and za=20 degrees ( see the simulation ). ... Let y2, y1 be the vertical positions of the two ends of this beam (y2 is the uphill coordinate). ... In reality, y2 is 1.464 degrees uphill from the center of the beam while the za optic axis is 1.1113 degrees uphill from the center of the beam suport. ...

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. ...
