scn2fits
NAME
scn2fits - make an image FITS file from a scn flow.
SYNOPSIS
scn2fits
[ -fits_name filename ]
[ -pipe | - | -nopipe ]
[ -shortheader | -longheader ]
[ -fitsdim number ]
DESCRIPTION
The command makes a FITS file from single scn dataset.
A stored FITS file is essentially single dimension image,
but you can make it as a three dimensional one formally.
In the latter case both 2nd and 3rd axis have a single component.
This means these axes are used only to assign the pixel position on the sky.
FILTER TYPE
.scn | scn2fits [ | .scn ]
OPTIONS
- -fits_name filename
- Name of output FITS file.
If you give this, all output FITS are the same name.
So, only the last scn is saved.
- When you give "-" or "auto" as the FITS filename,
actual FITS filenames are automatically made from input scn filenames,
which is the same main part with an extension "fit".
- -pipe | - | -nopipe
- When you give -pipe or
-, the command passes the scn-flow to the next step.
When you give -nopipe,
the command block the flow at this stage.
- -shortheader | -longheader
- When you give -shortheader,
the output FITS has a header shoter than 2880byte.
This means the header of the output FITS is only 1 block of FITS.
- When you give -longheader,
The command has no limit of size for the output FITS header.
- -fitsdim number
- Assign the nomical dimension of the output FITS.
- When you give 1, the data position on the sky is stored as
different FITS tag, such as GLONG and GLAT.
- When you give 3, the output FITS has 3 dimensional
and 2nd and 3rd axes shows the data position on the sky
besides the tags like GLONG and GLAT.
The coordinates are reffered to default coordinates assigned
in scn header.
DEFAULTS
