NAME
mShrinkCube - Reduce the size of a FITS cube
SYNOPSIS
mShrinkCube [-f] [-d level] [-m factor] [-s statusfile] in.fits out.fits factor
DESCRIPTION
A utility for reducing the size of a FITS cube, by averaging blocks of pixels by any
factor spatially and
by integer factors in the third dimension.
OPTIONS
-f Fixed-size flag - specify output size of image, instead of the size of blocks of
pixels to be averaged
-d level
Turns on debugging to the specified level (1-4).
-m factor
The (positive integer) factor by which to compress the cube in the third (usually
wavelength-related) dimension.
-s statusfile
Output and errors are sent to statusfile instead of to stdout
ARGUMENTS
in.fits
Input FITS cube
out.fits
Path to output FITS cube.
factor Size of blocks, in (fractional) pixels, to average. File size will be reduced by
1/factor squared. If the -f (fixed-size) flag is used, factor is the desired width
of the output image.
RESULT
[Normal mode]: FITS output image, reduced in size by a factor of (1/factor)^2 .
[Fixed-size mode]: FITS output image of width factor
