Results to be produced for comparisons
>
 * 1) Power spectra, as produced by the g2p.x Fortran utility and supporting IDL procedures, or directly with IDL; these should then be the same as the ones produced with **ps_power.pro** (NOTE: the varying compensation btw quantities is not implemented yet -- do it manually!) from the Fortran output (9 power spectra, arranged 3x3):
 * 2) Power spectra of rho and ln(rho), compensated with k^1 and k^(5/3), respectively
 * 3) Power spectra of B, compensated by k^2
 * 4) Power spectra of U, rho^(1/2) U, and rho^(1/3) U, compensated by k^2, k^(3/2), and k^(5/3), respectively
 * 5) Probability distribution functions (PDFs), primarily for log density and log(B^2/2), secondarily for velocity and velocity increments
 * 6) Structure functions for U and B; longitudinal and transverse; cf. the IDL and Fortran utitlities
 * 7) Image series, for 11 snap shots (at times 0.00, 0.02, ..., 0.20)
 * 1) Density projections; log of projected density and magnetic energy B^2/2, along the three axes
 * 2) The density projections should show log of average projected density, over the range [0.2,5.0] (average=1)
 * 3) The B2/2 projection should have the **same** normalization (if possible -- ie. if it shows "enough"), and otherwise another fixed range (specified in the figure).
 * 4) Density slice; ln for 5% of the z-values: IDL range (*,*,nz/2+-2.5%) for 256^3 data. Range: [0.01,10]
 * 5) One-layer density slice, IDL range (*,*,nz/2) [probably not meaningful for SPH data sets]. Range: [0.01,100]


 * //Please upload the data to CADAC and analyze it there, and please save the exact same data as is being plotted in an easily readable format!//**

As per earlier info, there are IDL analysis routines and Fortran binary utilities (with source code) available, to speed up the work, and to make sure we have a common basis for the comparisons.

Try to have as much as possible (in particular power spectra and images) done by 3pm, when we meet in the Founder's Room for coffee and result comparisons. Please put links to figures with the results on your wiki page (linked to your name on the workshop page).

Here's a link to some **relevant observations** for comparison, submitted by Alyssa Goodman on behalf of COMPLETE. More data is available upon request...just write to Jaime Pineda or Alyssa Goodman.


 * EXTERNAL PARTICIPANTS**: Please put results on your wiki page and send an email to Paolo or Aake to the effect that you have done so!
