**in=**- Input filename. No default.
**x=**- Pixel in X to print (0=1st pixel). By default it uses the center of the map.
**y=**- Pixel in Y to print.
**z=**- Pixel range in Z to select. By default all pixels are selected.
**scale=***fac1,fac2*- Output scaling factors for the spectral
axis (
*fac1*) and cube value (*fac2*). Note the mean/sigma output will also be scaled by*fac2*. [Default: 1,1]
