       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.

       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.

       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.

       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.
