[0801.1491] High resolution CMB power spectrum from the com
Posted: January 11 2008
Hi all,
The new results from ACBAR are impressive.
However I have some doubts on the following sentence:
"We see evidence for weak gravitational lensing of the CMB at >3-sigma significance by comparing the likelihood for the best-fit lensed/unlensed models to the ACBAR+WMAP3 data.".
How you can claim any evidence for weak lensing by just comparing the best fits ?
The "true" model can be 2 sigma away from the best fit in both cases...
I don't understand...
cheers
Alessandro
