NAME

       mTranspose - Re-order axes of multi-dimensional data sets

SYNOPSIS

       mTranspose [-d level] [-s statusfile] incube.fits outcube.fits [outaxis1 outaxis2 [outaxi3
       [outaxis4]]]

DESCRIPTION

       Montage (and a lot of other software) find it hard to work with WCS information  that  are
       not  connected  to  the first two axes in a datacube.  Rather than over-complicate all the
       cube-related software we have opted for having this utility for transposing the data.  The
       default  for  the  program  is to examine the cube and rearrange the data so the first two
       axes represent sky longitude and latitude but the user can optionally specify the order of
       the  rearrangement  themselves  (this also allows transforming reprojected cubes back into
       the original order for use by other programs).

OPTIONS

       -d level
              Turns on debugging to the specified level (1-3).

       -s statusfile
              mTranspose output and errors will be written to statusfile instead of stdout.

ARGUMENTS

       incube.fits
              Input FITS cube (3 or 4 dimensions).

       outcube.fits
              Output FITS cube.

       outaxis1 ... outaxis4
              The input axis numbers (1,2,3,4) in output order.

RESULT

       mTranspose rearranges the data value so the axes are in a different  order.   As  much  as
       possible, the FITS header keywords are renamed accordingly but as it is not alway possible
       to identify which parameters have axis "subscripts" it may be necessary to manually modify
       the headera(e.g., using mGetHdr / mPutHdr) after the fact.

       $ mTranspose in.fits out.fits 3 2 1 4
              [struct stat="OK", mindata=2234.5, maxdata=10234.4]

BUGS

       The drizzle algorithm has been implemented but has not been tested in this release.

       If  a  header  template  contains  carriage  returns  (i.e., created/modified on a Windows
       machine), the cfitsio library will be unable to read it properly, resulting in the  error:
       [struct stat="ERROR", status=207, msg="illegal character in keyword"]

       It  is  best  for the background correction algorithms if the area described in the header
       template completely encloses all of the input images in their entirety. If parts of  input
       images  are  "chopped  off"  by  the  header  template,  the background correction will be
       affected. We recommend you use an expanded header  for  the  reprojection  and  background
       modeling  steps, returning to the originally desired header size for the final coaddition.
       The default background matching assumes that there are no non-linear background variations
       in  the  individual  images  (and  therefore  in the overlap differences). If there is any
       uncertainty in this regard, it is safer to turn on the "level  only"  background  matching
       (the "-l" flag in mBgModel.
