NAME

imspace -- determine disk space used by IRAF images.

USAGE

imspace images

PARAMETERS

images

List of images to process.

vebose = yes

Print space used by each image in the input list? If this switch is set to no then only a summary of the space for all images in the input list is printed.

DESCRIPTION

This task determines how much space on disk is used by IRAF images. The size of the header and the pixel file are computed separately. The output of the task consists of three numbers: the space used by the image header, the space used by the pixel file, and the sum of both. If verbose is set, the space of each image is printed separately. Otherwise only the total space is printed. The image names are printed in the first column when the verbose switch is set, or when there is only one image in the input list.

EXAMPLES

1. Determine the size of a list of images using verbose output.

cl> imspace image*.imh verbose+
image1.imh                           9344     525312     534656
image2.imh                           9508     525312     534820
TOTAL                               18852    1050624    1069476

2. Determine the size of the same list of images, but without verbose output.

cl> imspace image*.imh verbose-
18852  1050624  1069476

BUGS

The image names MUST be fully specified, i.e. the extension cannot be ommited. This is because the task is using the file input/output (FIO) routines to open the image header and pixel files.
