Hi, Mike et al.I just recently upgraded my Macbook Pro to Lion. After a clean re-install of V2.15.1a using the "iraf.macx.x86_64" version on the downloads section of this site, I am getting pixels out of bounds error messages when I try to plot a spectrum using splot. Here are some details:
a) imhead on the image shows
295.J004056.72+410255.ms.fits[4543,1,3][real]: J004056.72+410255
i.e., it's one dimensional but had 3 bands.
b) Here's the exact error message:splot 295.J004056.72+410255.ms.fits
Image band to plot (1 (1): [okay, it's funny that come out as a funny face. It's a parenthesis 1 colon end parenthesis obviously...]
ERROR: Pixel subscript out of bounds (295.J004056.72+410255.ms.fits)
I did an unlearn splot to make sure things were okay.These spectra plotted fine before the upgrade to lion; i.e., when I was running
32-bit IRAF. I know there's an error logged about this, and the suggestion is to reinstall.
But I did that and it hasn't helped. Could it be that the "iraf.macx.x86_64"
on the download site isn't updated?Most other things work fine; i.e., I can do an implot dev$pix and display dev$pix and all works as expected.thanks!

Indeed, I think the file in the downloads area is bad. (It doesn't even have .tar at the end, although you can untar it like it was a tar file.) I found a version of the iraf.macx.x86_64.tar on another machine
of mine, installed that, and now splot works fine. In summary, I think there's something screwy with the file labeled iraf.macx.x86_64 near the end of the list on the downloads page.

Hi Phil,The .gz filenames are actually symlinks to the .tar.gz files, so even without the extension you get the same file either way. It may just be that the file you had locally that now works *is* the newer file and the original one was corrupted or didn't unpack correctly????There've been a number of 64-bit issues fixed recently but it would help if you could upload a FITS file to ftp://iraf.noao.edu/pub so I can try to reproduce the problem. If the data are integers with bscale/bzero header values then I think this problem is already fixed. Another thing that might help is if you could post/send me an "ls -l" output of the x_onedspec.e binary so I can figure out exactly which version you might be using.Cheers,
-Mike

Hi, Mike---I couldn't connect to the iraf ftp site, but I stuck an example
fits file at http://www.lowell.edu/users/massey/253.J004190.59+404856.ms.fitsIt works fine with the 64-bit version I downloaded in July (2.15.1a), but not what I picked
up the other day at the bottom of https://iraf.net/downloads/ page, which
also says 2.15.1a. You're right about the .gz extension in the download; apparently my downloader now un-g'zip things automatically and I'm left with a file with no extension,
which confused me.I've just downloaded it from the website again, ran install, and confirmed it fails on this file.

I see exactly the same thing with the version that DOES work.So, I'm looking at the wrong place. This is very repeatable (I've installed
each version multiple times to try this), so I repeat that I think if you go
to the downloads area and install the iraf.macx.x86_64.gz file rnear the
bottom, you'll see the same problem I'm seeing.

I get a 404 error trying to access the image URL.The binary to look at is noao$bin.macintel/x_onedspec.e

Sorry: my bad:

Mike, the version of x_onedspec.e that WORKS has a date of Mar 25 2011 and is derived from a tar file iraf.macx.x86_64.tar that I found somewhere.
The version that fails has a date of Feb 21, 2011. That is the one that you are linked to on the downloads page. So, I think all you have to do is change the downloads page link to the updated version and all is well.

I see what happened: The iraf.noao.edu archives were updated, but the download page points to a local iraf.net copy that uses the earlier files. I'm updating the files now and can confirm that your image works fine on macintel with the latest dev code.Thanks for the heads-up,
-Mike
