fitgauss

procedure fitgauss[, fit][, fitrms], [modelindex=long]

Interactive procedure that allows user to use the plotter and mouse buttons to specify regions and gaussians for fitting. Left Mouse Button: to mark regions (left then right) Center Mouse Button: to mark gaussians (center then width) Right Mouse Button: to calculate and show fits

Examples

   fitgauss,modelindex=10    ; fit gaussian and store model in DC 10
   show
   subtract,0,10,11          ; store residual in DC 11
   oshow, 11                 ; overlay residual
   oshow, 10, color=!yellow  ; overlay gaussian model
