Explanation of ngc3031 Files:
-------------------------------------------------------------------------------


-------------------------------------------------------------------------------

Notes:

* ngc3031_red.txt
  
  --> Reduction steps used in version1 of jiggle processing

* ngc3031_red_v2.txt
  
  --> Reduction steps used in version2 of jiggle processing

* flagging notes
  
  --> Notes on flagging of raw data

* MAKE_MOMENT_MAPS*
  
  --> Modified version of REDUCE_SCIENCE_GRADIENT provided by Remo Tilanus (orig
      inally for M51 reduction).  This script will produce 0th, 1st and 2nd moment map
      s at seven different clip levels (2.0, 2.5, 3.0, 3.5, 4.0, 4.5, and 5.0 sigma).
      Please note that only Step 3 of the script was executed.

Plots:

* ngc3031_nearest_totint20.eps, ngc3031_nearest_totint30.eps
  
  --> Contoured total integration maps with clip levels of 2.0 and 3.0 sigma res
      pectively. The first contour level is approximately one sigma.


* ngc3031_nearest_totint20_overlaid.eps, ngc3031_nearest_totint30_overlaid.eps

  --> Contours from the same total integration maps overlaid on a DSS optical im
      age. The first contour level is approximately one sigma.

* .pdfs version of each plot included
