How do I set the pixel size of the mosaic in MOPEX?
Posted by IRSA HelpDesk on 11 March 2013 01:48 PM
The pixel size can be set directly using the following keywords in the namelist, or in the Initial Settings module > General Options in the GUI:

MOSAIC_PIXEL_SIZE_X = -0.0003
MOSAIC_PIXEL_SIZE_Y = 0.0003

MOSAIC_PIXEL_SIZE_X is negative to follow the convention that CDELT1 is negative.

Alternatively, you can set the ratio of the input image pixel size to the mosaic pixel size using the following keywords:

MOSAIC_PIXEL_RATIO_X = 2
MOSAIC_PIXEL_RATIO_Y = 2
