<H2>DESCRIPTION</H2>
|
|
|
|
Reads a FITS file as input.
|
|
<A NAME="ixAAC"></A>
|
|
Produces a portable pixmap if the FITS file consists of 3 image planes
|
|
(NAXIS = 3 and NAXIS3 = 3), a portable graymap if the FITS file
|
|
consists of 2 image planes (NAXIS = 2), or whenever the
|
|
<B>-image </B>
|
|
|
|
flag is specified.
|
|
The results may need to be flipped top for bottom; if so, just
|
|
pipe the output through
|
|
<B>pnmflip -tb.</B>

|
<H2>OPTIONS</H2>
|
|
|
|
<P>
|
|
|
|
The
|
|
<B>-image</B>
|
|
|
|
option is for FITS files with three axes.
|
|
The assumption is that the third axis is for multiple images,
|
|
and this option lets you select which one you want.
|
|
<P>
|
|
|
|
Flags
|
|
<B>-min</B>
|
|
|
|
and
|
|
<B>-max </B>
|
|
|
|
can be used to override the min and max values as read from the FITS
|
|
header or the image data if no DATAMIN and DATAMAX keywords are found.
|
|
Flag
|
|
<B>-scanmax</B>
|
|
|
|
can be used to force the program to scan the data even when DATAMIN
|
|
and DATAMAX are found in the header. If
|
|
<B>-printmax </B>
|
|
|
|
is specified, the program will just print the min and max values and
|
|
quit.
|
|
Flag
|
|
<B>-noraw</B>
|
|
|
|
can be used to force
|
|
the program to produce an ASCII portable anymap.
|
|
<P>
|
|
|
|
The program will tell what kind of anymap is writing.
|
|
All flags can be abbreviated to their shortest unique prefix.
