Hi, I'm trying to pipe iraf output
into files but get "cannot write to"
errors;
e.g.,

ecl> imhead *.fits l- > list
ERROR: cannot open `list' for writing

Is there some flag I need to set in
login.cl? Or??

Thanks,

Why me Lord?Started by:dbrenner, 09/25/2009 12:02PM
In two scripts- one not used in days,
one after many successful executions-
fscan no longer reads whole lines from a
file. It first seems to read the file's
directory and then seems to treat _ as
an end of line.

Hello!

Which precession model is used by the
'precess' task of the 'noao.astutil.'
package? If it's the one suggested by
the IAU in 1984 (based on IAU 1976
system of astronomical constants), then
are there any plans to replace it by a
newer model IAU...

After this catchy title I really want to

is how old and outdated IRAF's code is.

I mean, the code itself is excellent,
but it was written in a completely
