NAME

stack -- Stack images along a specified axis, increasing the number of dimensions by one.

USAGE

stack input output

DESCRIPTION

The program stacks a list of images, producing an image with one greater dimension. Pixel [i,j,k] of the output image will be equal to pixel [i,j] of image k.

PARAMETERS

input [file list]

Names of the input files that are to be stacked. All images must be of the same size and have the same number of dimensions.

output [file name]

Name of the output file produced by this task.

(pixtype = real) [string, allowed values: real | long | int |

short | double]
Data type of pixels in the output image.

(ctype = "PIXEL") [string]

Value for the ctype keyword for the new axis.

(crval = 0.0) [real]

Value for the crval keyword for the new axis.

(crpix = 0.0) [real]

Value for the crpix keyword for the new axis.

(cdelt = 1.0) [real]

Value for the CD matrix keyword for the new axis.

EXAMPLES

1. Stack all images matching the template "inim*.imh". If there are 20 files with a size of 512 x 512, then "outim" will have dimension 512 x 512 x 20.

  im> stack inim*.imh outim
