******************************* PPT talks

-- Dec 10, 2007 -- PMSim image: Starfield maps, gal ellip maps, Shear
   profiles in shlets and imcat.  A611: starfields in ugr bands, mag
   vs. radius plot, first shr profiles.

-- Dec 13, 2007 -- A611: posmatching on objects, shlets-imcat match,
   star ellip map, shr profiles in g and r, comparing them in shlets
   and imcat.

-- Jan 28, 2008 -- A611: using masses from previous papers, first time
   we show the diagram, some star selection plots, 2D shearmap of the
   central cutout image in shlets and imcat, E and B modes from
   sextractor, ugr starmaps

-- Feb 4, 2008 -- A611: color color diags from SDSS, fg/bg galaxies
   using SDSS zp's

-- Feb 24, 2008 -- A611: [we never actually gave this talk] Cfht D1-D4
   fields mag histos, then color-color plots, using fg/bg separation,
   histos of fg/bg gals, CMD's, then back to SDSS, SDSS-LBC vs. mag,
   magiso vs. magaper

-- Feb 25, 2008, -- A611: LBC sextractor params, compare stars in the
   cutout in imcat and shlets, shlets fit to polynomial, interp'd psf
   at each position, careful star selection, class vs. the other
   handles on stars.  plot many properties,

-- Mar 12, 2008 -- A611: comparing order by order psf interps, in
   shlets and imcat, psfs on sep chips, stars are horiz stretched,
   gals have larger ellips, show the stars on stars tests, the flux is
   much more concentrated in shlets, corr funct intro.

-- Apr 4, 2008 -- Step2: even on odd star tests, table of mean e1,2
   and sigma's, after deconvln, corr of dif psf orders,

   A611: ellip of obj's in the 2 timeslice images, then the even and
   odd imgs.  corr funct of stars vs. galaxies.  stars before and
   after deconvln.  random stars.  ellip of stars, and dep on mag.
