Generic:
      nprepare  - Prepare NIRI data for reductions 
                  (update headers, derive variance and DQ planes)
      nresidual - Flag saturated pixels in the DQ planes of subsequent
                  exposures
  gnirs.nvnoise - Subtract vertical stripe noise and quadrant offsets

Imaging:
     nifastsky - Derive sky image for NIRI, median or min/max filtering
        niflat - Derive flat field and bad pixel mask for NIRI images 
         nisky - Derive sky image for NIRI, includes masking of objects
      nireduce - Reduce images from NIRI (dark or sky subtraction, flat)
      nirotate - Use WCS information to de-rotate NIRI images
    nisupersky - Make deeper object masks for NISKY
