2d spectra comparison

The 2D spectra for our channel flow simulation at Ret=800 (flood) is compared with Jimenez's channel data at Ret=950 (lines). This plot is at height y+=5.

Jimenez DNS channel data base can be found here: http://torroja.dmt.upm.es/channels/data/spectra/re950/2D/

Though the current plot is not smooth, the comparison is satisfied. I just need to run the simulation longer to get smoother contour plot. Moreover, I will also get the spectra data for our Ret=1600 on Archer.
