NAME

       mProjWWTExec - None

SYNOPSIS

       mProjWWTExec [-d level] tileLevel input.fits baseName hdrDir tileDir

DESCRIPTION

       Runs  mProjectQL  for  all  the  tiles  needed  for  a  WWT  TOAST  set.   Headers for the
       reprojection should already have been generated using mHdrWWTExec.  The base names for all
       tiles in a WWT TOAST set are the same, so that is needed as an argument, too.

OPTIONS

       -d level
              Turns on debugging to some level

ARGUMENTS

       tileLevel
              The  depth  of WWT TOAST tiles desired.  This should be no bigger than the depth to
              which header files were created.

       input.fits
              Input image to be reprojected into WWT TOAST tile FITS images.

       baseName
              Base name for tiles.  For instance, an output tile named "planck3102.fits" has  the
              base name "planck".

       hdrDir Directory with header templates.  These will have names like "tile3102.hdr".

       tileDir
              Directory for output images.

RESULT

       This  utility has two limitations.  First, it assumes that all the tiles are reprojections
       of a single input FITS file.  Montage has all the functions needed to use multiple inputs,
       even  coadding  across multiple images for any tile.  Second, all the output files are put
       in a single directory.  This may become unworkable if the tiles go deep enough.   Both  of
       these shortcoming can be easily overcome but the details will depend on the details of the
       input data so we have opted for a simple initial approach.

MESSAGES

       OK     [struct stat="OK", level=level, nimage=count]

       ERROR  Problem with FITS file.

       ERROR  Cannot find/address header directory [dir].

       ERROR  [dir] is not a directory.

       ERROR  Problem creating output tile directory.

       ERROR  Problem with output tile directory.

       ERROR  mProjectQL error message

EXAMPLES

       $ mProjWWTExec 4 Planck857.fits planck hdrs fits
              [struct stat="OK", level=4, nimage=341]

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.
