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)
