Downloads for Older Versions of IRAFStarted by:justinc, 07/11/2021 02:32PM
Are there any archive versions of IRAF
available for download anywhere? I can't
find them on NOAO.
I need 2.12.2a.

I am having recurring problems running

At some point, some IRAF tasks fails to
be able to open (existing and well
formatted) FITS files even though they
are indeed where they are.

Faike spectra IrafStarted by:Sparkles, 09/30/2010 04:30PM
Hi,

I'm trying to model a black body and see
what kind of spectra I would get out for
a given surface temp. Is there any way
of doing this using Iraf. i.e give it a
temp/peak wavelength and it models the
kind of spectra one would expect??

Many thanks ...

For a simple onedspec format fits file,
does the wavelength for pixel 1 refer to
the left (short wavelength) edge of the
pixel? or the center? I think the left
edge (as for an image WCS), but would
like to be sure.

And if I convert that fits file to ...
