| Abstract: |
With the advent of large format submillimetre arrays such as SCUBA, mapping of large areas of sky (several square degrees) becomes a feasible proposition. This paper discusses the dual-beam rastering technique used at the JCMT with particular emphasis on the data reduction algorithms used to deconvolve the chopped signal and remove the effects of sky-noise fluctuations. Direct deconvolution techniques (Fourier deconvolution) and non-linear methods (Pixon) are discussed. |
