mProjWWTExec - None
mProjWWTExec [-d level] tileLevel input.fits baseName hdrDir tileDir
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.
-d level Turns on debugging to some level
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.
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.

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.
