ccdprint - print out map values
ccdprint in=image [parameter=value]
ccdprint prints out map values in an image. The grid is specified
in x, y and z independantly, and can be any integer array, including implied
do loops, e.g. x=0,10,40:50:2,90,100 will print out values at x=0,10,40,42,44,46,48,50,90,100.
Note that the first grid point is 0 by convention in NEMO, though this
program can use offset=1 to "think" like a fortran array if that is convenient.
By default the matrix is printed such that the bottom left corner of the
output is the first pixel, as in (astronomical) image display. However,
by setting yreverse=f it can be printed with the first pixel on the top
right. This effect can also be achieved by an appropriate choice of y=NY-1:1:-1,
but the user is then required to know NY!
The physical coordinates can
be printed out optionally, where the output format is controlled by the
The following parameters are recognized in
any order if the keyword is also given:
- input file, in image(5NEMO)
format [no default].
- Grid coordinates in X to display. If no values
given, all gridpoints along this axis will be selected. Note the first gridpoint
is 0. By default this program will thus display the first pixel value. [Default:
- Grid coordinates in Y to display. See x=. [Default: 0].
- Grid coordinates in Z to display. See x=. [Default: 0].
- scale factor with which the data is multiplied before being displayed [default:
- Real-valued C-format expression (see also printf(3)
%10.6e, %5.2f) with which data and optional coordinate values are displayed
- Add a newline between each map value printed?
If false, all rows are printed on one line, and a blank line separates
different planes. [Default: f]
- Any combination of x, y and/or
z can be given, which labels the output with their X, Y and/or Z physical
values. If newline has been set to true, the selected labels are printed
for each coordinate selected (this produces a nicely formatted table that
can be easily used by subsequent analysis programs), whereas the default
value would print a row of X coordinates before each printed plane , and
a left column of Y coordinates, if selected. Each new plane is preceded
with a plane coordinate also. This option is more readable for humans, but
not easily processed by other programs. [Default: no labels].
X,Y,Z be 0- or 1- based. NEMO images use 0-based images, but to appease fortran
users, 1-based input can be given here if this parameter is set to 1. Default:
- Reverse printing the Y values. By default this is true, such
that the printed layout resembles how it is normally displayed in an image
display (at least astronomically). [Default: t]
- Print out X,Y,Z
labels in physical or pixel coordinates. By default physical. [Default: f]
- Should input (x,y,z) be paired up [f]
- Print a sequence using
