[b:a8ae29fd9f]Subject: [/b:a8ae29fd9f][b:a8ae29fd9f]zerocombine in mscred[/b:a8ae29fd9f]
I was trying to reduce some Palomar mosaic data within mscred,
using an instrument description file in a private mscdb kindly
provided by a previous user. Anyway - I must be missing something
in calling the mscred version of zerocombine, because it
consistently gives a string of "Warning: FXF: must specify which
FIST extension..." messages. I even explicitly called 
mscred.zerocombine to make sure it wasn't trying to call the
ordinary one from ccdred.
Hints appreciated...
Thanks,
Bill Keel

Hi Bill,
I can't tell just from the information you sent what is the problem.  First we should determine if other tasks seem to understand the format.  The first command you should try is
mscextensions <file>
This should expand the multiextension file into the extensions.  Because it is a hidden task that is used to expand the multiextension files into a list of extension references the command cannot be abbreviated.  It is essentially the same task as proto.imextensions so you could use that and look at the help page if you are interested.
Does mscdisplay work?
The next thing to determine is if the error is coming from ccdproc or combine which are both part of zerocombine.  There are a few ways to determine this.  One is to turn off the process flag in zerocombine so you know it is not calling ccdproc first.  The other thing is to turn on the tracing with "d_trace".  It is a toggle command so you invoke it again to turn off tracing.   It spews out a lot of stuff, most of which is not too useful.  The most useful thing is when it shows the last command executed before the error message is given along with all its parameters.
If you want to send me the tail of the d_trace output or a header dump of a Palomar mosaic along with the mscdb file and parameters I can take a look.  Note that to dump a header from a mosaic I suggest
ms> mscccmd "imhead $input l+ > hdr" <filename>
Msccmd is a useful command that expands an MEF into single image references and then passes this on to any IRAF command which works off a list of single images; in this case imhead.
Cheers,

OK, I'll try those (just now getting our machines back after the
latest hurricane pulled trees down on all those power lines).
Meanwhile, I had a thought - on that RedHat machine, I typically
run with imagetype=fits to ease things when crossmounting with
my SGI. Could that cause such a problem, or does it automatically
create MSC-style FITS files upstream?
Thanks, and I'll get back with the results of your queries,
Bill

Hi Bill,
The news is showing quite a major disaster in your part of the country.  I hope recovery goes well for you and eveyone else.
MSCRED requires use of imtype="fits".  In fact, when you load MSCRED is forces that.  So if you run with imtype=fits then that would not cause a problem.  Get back to me when you can.  I'll be gone 9/4 to 9/16 though I'll check mail occasionally.
Best wishes,
Frank

Trying your ideas in order:
mscextensions seems to work:
mscextensions aug05.047
aug05.047[1]
aug05.047[2]
aug05.047[3]
aug05.047[4]
aug05.047[5]
aug05.047[6]
mscdisplay works 
Aha! If I set process=no in zerocombine (invoked from a session in which
I have not explicitly loaded the ccdproc stuff), it works. Now to see whether
I have a downstream problem. Just in case, I dumped a sample header (below). 
Thanks,
Bill

Hi Bill,
OK we now know it is a problem with running ccdproc.  You make the comment about not explicitly loading ccdproc stuff.  This indicates you may have a confusion about packages.  You should only load mscred and not ccdred.  Mscred contains version of things for MEF files including a version of ccdproc.  If you have both mscred and ccdred loaded then there can be a confusion in tasks.  The imred.ccdred package does not understand MEF files and so if you give it an MEF file as input you will get a message about not specifying an extension like you report.  So make sure you only load mscred when working with the Palomar data.  Check you don't load ccdred automatically in your login files.
Yours,

Followup - my previous problem had been due to confusion in my mind
between ccdproc the package and ccdproc the task within mscred.
I was following a set of cookbook instructions which I misread
as saying to load ccdproc as well as mscred. When I don't do that,
I get much farther.
Next question - I'm trying to retrieve astrometric coordinates with
mscgetcatalog, and keep getting a null coordinate file. I use, say,
        input = "aug06.033.fits" List of Mosaic files
       output = "test33"        Output file of sources
      (magmin = 14.)            Minimum magnitude
      (magmax = 19.5)           Maximum magnitude
     (catalog = "CADC:USNO-A2") Catalog
        (rmin = 21.)            Minimum radius (arcmin)
        (mode = "ql")           
and get nothing when I use catalog names NOAO:USNO-A2 or usno2@cadc.
No actual error message, but no star list either. What am I missing?
There are RA/dec keywords in the FITS header (see below) - are they
in the right format?
Thanks,
Bill Keel

Hi Bill,
I'm sorry for the delay in replying.  MSCGETCAT uses the image WCS.  It does not look at keywords like RA and DEC.  So to use it you would have to add a WCS.  However, MSCGETCAT is just a simple script that uses the hidden task (in the MSCRED package) called GETCATALOG.  If you "lpar" this (you can't abbreviate hidden tasks) you will see that it can be used either with an image or with explicit RA and DEC values.
Yours,
Frank
