Description

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

Options

       filename
              Name of IRAF image header file or FITS file. This must be present.

       @coordfile
              File with x y coordinates as first two tokens on lines

       xrange yrange
              Image  coordinate  x  and  y ranges as x1-x2 y1-y2 or lists of x and y coordinates, where x is the
              horizontal and y is along the vertical axis starting at 1,1 in the lower left corner of the image.
              If either range is "0", all of the coordinate values along that axis are displayed.

       -d number
              Set the number of decimal places in displayed pixel values

       -e pixel value range
              Print range of pixel values in specified image region

       -f name
              Write specified region to a FITS file

       -g num Keep pixels with values greater than this

       -h     Print file name on line above pixel values

       -i     Ignore first token per line of coordinate file

       -l num Keep pixels with values less than this

       -m     Print mean of pixel values in specified image region

       -n num Number of pixel values printed per line

       -o format: Output format in C style without leading %

       -p     Label pixel rows and columns

       -r num Radius (<0=box) to extract in degrees/arcsec

       -s     Print x y value with no punctuation

       -t     Separate columns in table with tabs instead of spaces

       -v     Verbose header with more about the image and label pixel coordinates from input list

       -y     Display x as rows (vertically) and y as columns (horizontally)
