      Users may specify mosaics according to the following parameters: 

            location            -- Central object name or coordinates.
            dataset             -- Archive dataset name and wavelength band. (default "2MASS J")
            size                -- Image width/height in degrees. (default: 0.5)
            scale               -- Pixel scale (defaults are e.g. 1 arcsec for 2MASS, WISE; 0.4 arcsec for SDSS).
            coordinateSystem    -- Options include "Equatorial J2000" (default), "Galactic", etc.
            backgroundMatching  -- Rectify background to a common level across images ("True" is recommended).
            outfile             -- Default: "mosaic.fits".
            workdir             -- Working directory (cleared out for every run).
            verbose             -- Show (and retain) a list of the processing steps (recommended for troubleshooting)

      Note: "location" allows for flexibility in entering an object position (which can be either an object name
             or sky coordinates). The following are all valid values:

            M51
            00h 42m 44.35s +41d 16m 08.6s  EquJ200 (default)
            10.68 6 +41.269 EquJ2000 (efault)
            00h 40m 00.11s +40d 59m 42.9s EquB1950
            10.0005 +40.995 EquB1950
            121.174 -21.573 Gal
            27.849 +33.348 EclJ2000
