CONPL Type: Task Use: Plots the convolving functions available in AIPS, both in the convolving space and in its Fourier transform. Adverbs: INNAME......Input file name (name) Standard defaults. (Used only to attach the plot file if any.) INCLASS.....Input file name (class) Standard defaults. INSEQ.......Input file name (seq. #) 0 => highest. INDISK......Disk drive # of input file. 0 => any. XTYPE.......Convolution function type in X-direction 1=Pillbox, 2=exponential, 3=Sinc, 4=Exp*Sinc, 5=Spheroidal, 6=Bessel/x*exp <= 0 or > 6 -> 5. XPARM.......Array containing parameters for XTYPE. See HELP UVnTYPE when n=convolution type. OUTTEXT.....If not blank, list the two functions plotted in a text file named by OUTTEXT. It will be created or appended as appropriate. BPARM.......Plot control parameters: Top plot (Convolution function): 1 = Minimum of X-axis. 2 = Maximum of X-axis (if <= BPARM(1) do self-scale in X). 3 = Minimum of Y-axis. 4 = Maximum of Y-axis (if <= BPARM(3) do self-scale in Y). Bottom plot (1 over FFT of convolution function or convolved convolution function) 5 = Minimum of X-axis. 6 = Maximum of X-axis (if <= BPARM(5) do self-scale in X). 7 = Minimum of Y-axis. 8 = Maximum of Y-axis (if <= BPARM(7) do self-scale in Y). 9 : <= 0 => do the FFT of the convolving function in the bottom plot <= -1 => do the signal-to-noise ratio (for uniformly sampled synthesis imaging = FFT of convolving function divided by FT of SAMPLED autocorrelation of the convolving function > 0 => convolve the convolving function with a Gaussian of full width at half maximum of BPARM(9) pixels and polot that in the bottom plot. 10 : 0 => plot 1 / FFT of the convolving function (or N/S) 1 => plot the FFT of the convolving function (or S/N) 2 => plot log10 of the FFT of the conv. function (or log(S/N)) DOCIRCLE....False (<= 0) means that tick marks are short lines extending inward from the plot borders. True (>0) requests that a full coordinate grid be drawn. DOTV........> 0 => plot directly on the TV device, otherwise make a plot file for later display on one or more devices (including the TV if desired). GRCHAN......Graphics channel (1 - 7) to use for line drawing. 0 => 1.
