       mViewer - Render multi-dimensional images and large-scale images


       mViewer generates a JPEG image file from a FITS file (or a set of three FITS files in full
       color).  A data range for each image can be defined, and the data can be stretched by  any
       power  of  the  log() function (including zero: linear) or using custom gaussian histogram
       equalization algorithms.  Pseudo-color color tables can be applied in single-image mode.

       mViewer can also generate overlays on the image of coordinate grids, source catalogs (with
       scaled symbols), image outlings from metadata tables, plus various markers and labels.

       Along  with  a  few  other  Montage modules, mViewer can be wrapped to support interactive
       image analysis from Python or through AJAX web interfaces.

       The functionality of mViewer goes beyond what is reasonable to capture in a man page.  The
       user is therefore directed to the mViewer documentation suite.

       A complex example with a catalog overlay (symbol size, shape and color controlled by table
       columns), image metadata, a coordinate grid and some custom labeling:


       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.
