PRPLT: Plots "profiles" of the average of an image on axes
INPUTS
INNAME Grey scale image name
INCLASS Grey scale image class
INSEQ 0.0 9999.0 Grey scale image seq. #
INDISK Grey scale disk drive #
BLC 0.0 4096.0 Bottom left corner of image
0=>entire image
TRC 0.0 4096.0 Top right corner of image
0=>entire image. See HELP!
DOPROFIL -1.0 7.0 1 => profile vs X
2 => profile vs Y
4 => profile vs Z
3 => profiles 1 and 2
5 => profiles 1 and 4
6 => profiles 2 and 4
7 => all 3
PIXRANGE Min,Max of image intensity
0 => entire range.
XYRATIO 0.0 10.0 X to Y axis plot ratio. 0 =>
header inc or window ratio.
LTYPE -410.0 410.0 Type of labeling: 1 border,
2 no ticks, 3 standard, 4 rel
to center, 5 rel to subim cen
6 pixels, 7-10 as 3-6 with
only tick labels
<0 -> no date/time
DOTV -1.0 1.0 > 0 Do plot on the TV, else
make a plot file
GRCHAN 0.0 8.0 Graphics channel 0 => 1.
HELP SECTION
PRPLT
Type: Task
Use: PRPLT does graphics plots from an image cube averaged along each
axis. The axis labels for longitude and latitudes are not done
with the same accuracy as the labels on TV and other grey-scale
displays. The longitudes are scaled by the reference pixel
latitude and latitudes, longitudes, velocities, and other axes
are treated as linear functions which is approximately correct
over small-angle images.
Adverbs:
INNAME......Image name for profile. Standard defaults.
INCLASS.....Image class for profile. Standard defaults.
INSEQ.......Image seq. # for profile. 0 => highest.
INDISK......Disk unit # for profile. 0 => any.
BLC.........Bottom Left Corner of the image (0,0) means (1,1).
TRC.........Top Right Corner of the image: (0,0) means top right
corner of map.
DOPROFIL....1 => profile vs X (average along Y and Z)
2 => profile vs Y (average along X and Z)
4 => profile vs Z (average along X and Y)
3 => profiles 1 and 2 (X and Y)
5 => profiles 1 and 4 (X and Z)
6 => profiles 2 and 4
0, 7 => all 3
If any axis has only 1 point (BLC(i)=TRC(i)), that plot
will be surpressed.
PIXRANGE....Min,Max of plot intensities. 0 => entire range
XYRATIO.....The ratio of the X-axis to Y-axis plot scale.
0 => 1 of DOTV false, 1.4 if DOTV true.
LTYPE.......Labelling type, see HELP LTYPE for details:
1 = border, 2 = no ticks, 3 or 7 = standard, 4 or 8 =
relative to ref. pixel, 5 or 9 = relative to subimage
(BLC, TRC) center, 6 or 10 = pixels. 7-10 all labels
other than tick numbers and axis type are omitted.
Less than 0 is the same except that the plot file
version number and create time are omitted.
Add n * 100 to alter the metric scaling.
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 => use multiple graphics planes for the various parts
of the graphical drawing.
