Description

15       Display the values of list of specified pixels or ranges of pixels in a
16       FITS  or  IRAF  2-D image. Pixel values from a file of x y pairs may be
17       displayed
18

Options

20       filename
21              Name of IRAF image header  file  or  FITS  file.  This  must  be
22              present.
23
24       @coordfile
25              File with x y coordinates as first two tokens on lines
26
27       xrange yrange
28              Image coordinate x and y ranges as x1-x2 y1-y2 or lists of x and
29              y coordinates, where x is the horizontal and y is along the ver‐
30              tical  axis  starting  at  1,1  in  the lower left corner of the
31              image. If either range is "0",  all  of  the  coordinate  values
32              along that axis are displayed.
33
34       -d number
35              Set the number of decimal places in displayed pixel values
36
37       -e pixel value range
38              Print range of pixel values in specified image region
39
40       -f name
41              Write specified region to a FITS file
42
43       -g num Keep pixels with values greater than this
44
45       -h     Print file name on line above pixel values
46
47       -i     Ignore first token per line of coordinate file
48
49       -l num Keep pixels with values less than this
50
51       -m     Print mean of pixel values in specified image region
52
53       -n num Number of pixel values printed per line
54
55       -o format: Output format in C style without leading %
56
57       -p     Label pixel rows and columns
58
59       -r num Radius (<0=box) to extract in degrees/arcsec
60
61       -s     Print x y value with no punctuation
62
63       -t     Separate columns in table with tabs instead of spaces
64
65       -v     Verbose header with more about the image and label pixel coordi‐
66              nates from input list
67
68       -y     Display x as rows (vertically) and y as columns (horizontally)
