NGAUSS 0.0 4.0 No of Gaussian components. @ Output adverbs GMAX @ Max value of the components. GPOS @ Positions of the components. GWIDTH @ Width at 1/2 max amplitude. ---------------------------------------------------------------- TVSET Type: verb Use: To allow interactive setting of parameters for 1D Gaussian fitting (slices) by using the TV cursor. The slice to be fitted must have already been plotted on the TV graphics screen. Move the TV cursor to the specified points and press any button (A, B, C, or D) to enter the parameter. Instructions will appear on your input window. TV1SET n allows only component n to be set. Adverb: NGAUSS......The number of gaussian components (1 through 4). Output adverbs: GMAX........Initial guess of maximum amplitudes. GPOS........Initial guess of positions of the components in GPOS(1,i). GPOS(2,i) not used. GWIDTH......Initial guess of widths at 1/2 max amplitude in GWIDTH(1,i). GWIDTH(2,i) and GWIDTH(3,i) are not used. Note that the units of GMAX, GPOS, and GWIDTH are those in the plot (e.g. mJy, arc sec or Jy, degrees or ??). ----------------------------------------------------------------
