Mac 10.7 and V2.16

[paco]

Hi,

I recently installed IRAF v 2.16 on a new Mac running OS10.7.4 (I forget which cat this is!). I can run basic IRAF tasks just fine. But there are a number of problems that crop up.

1. When I try to do access help (anything), I get messages about a bunch of package names not being unique, followed by:
PANIC in `/Users/Shared/iraf/iraf/bin.macintel/x_system.e': Memory fwa has been corrupted
ERROR: segmentation violation

2. I need to use several mscred tasks; most recently msctpeak. The task starts up OK and I can interact with my display, BUT, when I try to fit a selection of stars I've centered, I get:
ERROR: floating point overflow
"graphics=graphics, cursor=cursor)"
line 209: mscfinder$tpltsol.cl (hidden task)
called as: `tpltsol (image=t70005, table=tmp$iraf3374f.fits, database=coords.db, imupdate=yes, tabupdate=yes, refitcat=yes, dssheader=no, ra_ref=23:56:40.00, dec_ref=62:10:00.00, eq_ref=2000.)'
called as: `tpeak (image=t70005, table=tmp$iraf3374f.fits, database=coords.db, objects=, ra_ref=23:56:40.00, dec_ref=62:10:00.00, eq_ref=2000., update=yes, interactive=yes, autocenter=no, autodisplay=no, boxsize=9, xscale=100., yscale=100., xshift=0, yshift=0, reselect=yes, subsample=1, frame=1, marker=circle, omarker=plus, goodcolor=blue, badcolor=red)'
"goodcolor=goodcolor, badcolor=badcolor)"
line 172: mscfinder$msctpeak.cl
called as: `msctpeak (images=t70005)'

I'm sure that I've somehow fouled up the installation or something, but I am such a systems idiot that I really don't know how to fix this.

Thanks!

Hi,

For the msctpeak problem try a) using nfextern.msctools.mscfinder.msctpeak (i.e. the version in the nfextern package which you may need to add to your extern) and b) in your IRAF environment (either during your session or in your login files)

Hi Frank,
I never really resolved the problem described above, but I now have this same machine running IRAF ver 2.15 (newly installed, and which I need for Gemini compatibility) on a Mac, OS10.8.

Now, when I try to run the msctpeak (from mscred.mscfinder), it displays the image, but does not mark my catalog stars. I get the following message:
mscfinder> msctpeak
List of WCS calibrated Mosaic images: t10015
List of ra(hr), dec(deg), optional id: m31_ucac4_hrs.txt
Database for astrometric fit (coord_data):
ERROR: Table `/tmp/iraf207f' does not exist or cannot be opened.
"goodcolor=goodcolor, badcolor=badcolor)"
line 172: mscfinder$msctpeak.cl
called as: `msctpeak ()'

So I then tried installing nfextern, as you suggested above, and repeating the process. I then opened up a new IRAF window, navigate to nfextern and then try msctpeak from that package, it displays the image, marks the stars, and allows me to center them. But then when I hit "f" to do a fit, I get a different message, essentially the same one that I reported in my post above, from December.

msctpeak is a great routine--very helpful--so I hope you can help me sort this out.

Thanks,
Frank W.
