NAME

fim2lst -- Create an output file containing a list of the coordinates and value of the pixels in an input FITS image.

USAGE

        fim2lst infile outfil 

DESCRIPTION

This task will read data from a FITS image file (1-d, 2-d or 3-d) and write the X (Y, Z) coordinates and the data value of all the non-zero pixels to an output FITS file. Zero-valued pixels can be included by setting the copyall parameter. Now supports writing the world coordinate column(s) for 1- and 2-d images.

PARAMETERS

infile [filename]

Name of the input FITS image or image extension.

outfil [filename]

The name of the FITS file to which the list of pixels is written.

(x = X) [string]

Name for the column in the output file containing the X coordinate of the pixel.

(xcoord = XCOORD) [string]

Name for the column containing the pixel X world coordinate.

(y = Y) [string]

Name for the column in the output file containing the Y coordinate of the pixel.

(ycoord = YCOORD) [string]

Name for the column containing the pixel Y world coordinate.

(z = Z) [string]

Name for the column in the output file containing the Z coordinate of the pixel.

(value = VALUE) [string]

Name of the column in the output file containing the value of the pixel.

(extnam = "") [string]

Value to be written to the EXTNAME keyword in the output extension.

(copyall = no) [boolean]

If set, this will force fim2lst to copy all pixels, including zeros.

(clobber = no) [boolean]

If true, an existing output file of the same name will be overwritten.

EXAMPLES

1. Construct a list of non-zero pixels in the input image.fits file and write the list to the output file called utfile.fits.

         ft> fim2lst image.fits outfile.fits

NOTES:

FIM2LST uses dynamic memory to read in the entire image at one time. If the requested image is larger than the available system memory, an error will be reported
