NAME

       mHdrWWTExec - None

SYNOPSIS

       mHdrWWTExec [-d level] tileLevel hdrDir

DESCRIPTION

       Runs mHdrWWT to create all the header template file needed for WWT TOAST tiles down to a specified level.

OPTIONS

       -d level
              Turns on debugging to the specified level

ARGUMENTS

       tileLevel
              The  depth to which the tiles are created.  Level 0 is just produces the all-sky header, 1 is that
              plus the four main quadrants, etc..  Level 4 produces files like "tile3102.hdr".

       hdrDir Output directory for the header files.

RESULT

       The set of header files.

MESSAGES

       OK     [struct stat="OK", level=n, nheader=nheader]

       ERROR  Problem creating output header directory.

       ERROR  Problem with output header directory.

       ERROR  [hdrDir] is not a directory.

       ERROR  mHdrWWT error message

EXAMPLES

       $ mHdrWWTExec 4 hdrs
              [struct stat="OK", level=4, nheader=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.
