I BICEP2's Mis-Estimation: Was Not CIB Subtraction the Cause?

[windy miller]

When BICEP 2 announced they had discovered primordial B modes they used a slide from Planck to model dust emission. The slide said the estimations were 'Not CIB" subtracted. See this blog that came out at the time:

My question is , was this the major cause of BICEP's mis estimation ? Had they corrected for this properly would the signal have gone away or was the source of the error elsewhere?

As far as I can remember they were mistaken by dust within the milky way.

yes I know that but my question is more specific than that . The question is what the mis estimation of the dust mostly caused by the fact that BICEP didn't take account of the fact that the Planck slide they used wasn't CIB subtracted.
