#### LRO Narrow Angle Camera (NAC) [¶](#LRO-Narrow-Angle-Camera-\(NAC\)-)



TBD

LRO NAC consists of two cameras, with both acquiring image data at the same time, denoted with ``L`` and ``R``. 



What follows is an example of processing the experimental data records (EDR) for images M104318871LE and M104318871RE. 



Visit http://wms.lroc.asu.edu/lroc/search and search for these. Once you have the full URL, they can be downloaded with ``wget``. This will result in two  files, named M104318871LE.img and M104318871RE.img.



We convert each .img file to an ISIS .cub camera image, initialize the SPICE kernels, and perform radiometric calibration and echo correction. Here are the steps, illustrated on the first image::

   

    lronac2isis from = M104318871LE.IMG     to = M104318871LE.cub

    spiceinit   from = M104318871LE.cub

    lronaccal   from = M104318871LE.cub     to = M104318871LE.cal.cub

    lronacecho  from = M104318871LE.cal.cub to = M104318871LE.cal.echo.cub



The obtained images can be inspected with ``qview``.
