Who may help?
After converting HST-images (WFPC2) from fits- to sdf-files (fits2ndf) I
try to open the sdf-file on my linux-PC (tcsh-shell) with the kappa-command:
"display filename device=xwindows mode=faint"
and get the following answers:
!! The NDF filename is not 2-dimensional
! Display: Failed to display an image of a one- or two-dimensional
data set.
! Application exit status SAI__ERROR, Error
The FITS-Header of the file reveals
NAXIS = 3
NAXIS1 = 800
NAXIS2 = 800
NAXIS3 = 4
"ndftrace filename" shows:
No. of dimensions: 3
Dimension size: 800 x 800 x 4
Pixel bounds: 1:800, 1:800, 1:4
Total pixel: 2560000
It seems to me, that this may be the consequence of the fact, that the
fits-File contains 4 different parts of the whole WFPC2-image. If this
is true, is there a possibility to extract these 4 images out of the
fits-file, to convert them to sdf-Files, and to handle them with
kappa-commands?
