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
-

- -r num
-
Radius (<0=box) to extract in degrees/arcsec
- -s
-
Print x y value with no punctuation
- -t
-
