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
- 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)
