BACK N1 N2 PHASE WCEN GAMMA KXLO KXHI NKX KYLO KYHI NKY C1 C2 -- Back projects spectra This computes integrals over sinusoidal paths through the data and plots the results as an image in which the intensity at each point is the value of the integral. The integral is carried out NKX*NKY times so it is best to start with low values to get an idea of the result. In order to get a filtered back-projection you should run BCKFIL first. Parameters: N1 -- First spectrum N2 -- Last spectrum PHASE-- Name of phase to use WCEN -- Rest wavelength GAMMA-- Systemic velocity KXLO -- Lowest Kx value KXHI -- Highest Kx value NKX -- Number of Kx values KYLO -- Lowest Ky value KYHI -- Highest Ky value NKY -- Number of Ky values C1 -- Plot level for lowest colour index C2 -- Plot level for highest colour index Set C1=C2 for auto-scaling from lowest to highest values. If C1=C2=0. they will be set to the autoscaled values on leaving the routine. Otherwise they will be left alone. If you choose NKX and NKY to be large, there may only be enough memory to plot the image in sections, in which case the autoscaling option only scales on the first chunk to be plotted.Related commands: bckfil , bndf
