coordinate grid

HELP SECTION
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.
