GOAL: Look at CBI data again.  Main goal here is to look at the only
higher level imaging tool - map - again.

1. Make ms = cbi0844.ms from cbi0844.uvf
   Get a bunch of errors like

    ITS card 75: PSCAL7  =                    1 

   but it seems to finish OK

2. Try "map" tool again

   SelectionManager - need to be able to bring up a viewer with the
   field names in the FIELD table of the ms and send to selection box

      Have to do this manually, using the CatalogGUI.  Find only NAME
      is "C0844-0310".  Put in fieldnames box.
 
   Same for spectral window id

      Look at SPECTRAL_WINDOW table, find rows 1-10 corresponding to
      IFs.  I assume the spectral window ids should then be 1-10
      (but there is no ID column).  Can I just set it to 1:10 ?
      Try...

   Hey, where do I just go ahead and make an image???  Doesnt seem to
   be under any solvers.  I think this is a dead end, just go back to
   the regular imager/calibrater

3. Try imager, with 

          setdata: spwid 1:10
          setimage: nx = ny = 256; cellx = celly = 1arcmin

   but get error

      No useful data: weights all zero

   Maybe the selectdata didnt work right, try

          setdata: spwid [1,2,3,4,5,6,7,8,9,10]

   But get same error.  Data weights must be screwed up.

   Try weighting

          weight: type=briggs; rmode=robust; robust=0

   Maybe it worked this time...

   Check in image.view() - indeed that worked!  Im not sure why the
   weighting was screwed up to begin with, maybe something in the fits
   file.

   Map statistics:  rms = 1.6 mJy/bm  max = 6.8 mJy/bm  min = -6.6 mJy/bm

DONE FOR NOW.
